Itchy, pinpoint rashes on the skin. Fungal infections and lichen. Treatment methods and preventive measures

Rash is one of the most common reasons visits to a dermatologist not only in children, but also in adults. And their concern is well founded. The appearance of rashes on the body of an adult indicates one of two things:

This is a skin disease, a type of dermatitis. Any dermatitis must be treated immediately, otherwise it threatens to develop into chronic form. There are a number of diseases of different nature affecting exclusively the skin: seborrheic dermatitis, acne, lichen and much more. A rash on the body of an adult can also be a manifestation of urticaria, neurodermatitis, or soft fibroma. Sometimes it appears in women.
The rash is not the main disease, but a symptom of a serious illness in the body. Our skin is a kind of indicator that signals the presence internal pathologies. And it makes sense that the rash won't go away until you treat the underlying disease.

The most important step in treating rashes in adults is diagnosis. A dermatologist will first of all pay attention to the nature of the rash.

Types of rashes in adults

Experts identify different types of rash, the exact definition of which often determines the correct diagnosis:

Stains

They are located at skin level, without rising above the surface. Depending on the color, roseola (red spots), pigmentation ( brown spots), vitiligo (white spots).

Blisters

Raised above general level skin elements with a rough surface.

Bubbles

Formations on the surface of the skin filled with liquid contents.

Macules

Patches of red, pink, brown, white or other colors that are flush with the rest of the skin.

Ulcers and erosions

Areas of violation of the integrity of the skin, often covered with secretions of one kind or another.

Papules

A rash in an adult on the neck and other parts of the body often takes the form of papules - nodules of varying sizes located in the depths.

Rash in an adult: causes of appearance

By the appearance and location of the rash on the body in adults, one can often make an assumption about the nature of the disease and find out the root cause of the rash.

Infectious rash

Transparent bubbles with a diameter of half a centimeter, which are localized in the abdomen and lower back, on the chest, on the shoulders and the back of the head, can be a symptom of shingles. The appearance of rashes occurs against the background pain symptom and disturbances in the sensitivity of affected skin areas.
Pemphigus appears as single small blisters in the back and chest. After a few days, they heal on their own, and yellow crusts form at the site of the rash.
Small vesicles and papules on the hands, wrists and feet that are very itchy can be a symptom of scabies. If you suspect this disease, you should carefully examine the skin for the presence of scabies - slightly protruding lines on the skin with a small bubble at the end.
When lichen rosea forms on the back or chest of the patient, pink spot oval shape with a little flaking in the middle. Later similar spots appear on the body, individual blisters and vesicles may form.
Herpes is accompanied by the appearance of small transparent bubbles resembling spheres in shape on the mucous membranes (most often on the lips) and on the face. The bubbles are close to each other, so from afar they resemble one big sore. After a few days, the bubbles darken and begin to shrink to form dark brown or yellowish crusts.
With syphilis, the rash is secondary symptom. It appears unexpectedly, resembles small symmetrical spots located in typical localization areas - these are the outer sides of the forearms, under the mammary glands, in groin area and between the buttocks.

Rashes of non-infectious origin

With seborrheic dermatitis, the rash is located in areas of the skin with a large number of sebaceous glands– face, scalp, skin folds. Yellow-red spots of different sizes have a greasy surface and peel.
Acne appears on the face and torso (mainly on the back and chest) during puberty. In an adult, they can occur due to a violation hormonal levels. There are different types of acne - punctate comedones, papules and pustules, globular acne. Almost all of them leave scars on the skin.
Round blisters of different sizes, pale red in color, which gradually merge with each other, and also itch, may be a symptom of urticaria.
If on the head (its scalp), on the elbow bend of the forearm with inside, pink-red papules, covered with scales, formed under the knees, and over time they began to enlarge and merge with each other, most likely this is psoriasis.

Allergic rash in adults

Such rashes resemble hives in appearance, but are accompanied by less severe itching. The elements vary in appearance: red spots with areas of peeling, crusts, small blisters.
Against the background of toxicoderma (when the allergen has entered the body, and not as a result of skin contact with the irritant), inflammatory spots, blisters and papules appear on the skin. They are distinguished by their symmetrical arrangement.

Allergic rashes on the skin - this is a special reaction of the body to one or more irritants. They can present as peeling, blisters, spots, ulcers, erosions, swelling, red pimples, cause itching and form a crust on the skin. A skin rash can form on any part of the skin. Allergic reactions most often appear on the hands and face, and infectious reactions on the surface of the body.

Skin rash: causes

A skin rash on the human body occurs due to an allergy or an infectious disease. Allergic rashes are a consequence of malfunctions of the immune system. As soon as an allergen molecule enters the body, it immediately begins to synthesize antibodies, which subsequently begin to attack skin cells. Below is a list of the main allergens:

Food (most often the list of allergens includes honey, citrus fruits, nuts, chocolate and dairy products);
Medications;
Fabrics (synthetics and wool);
Cosmetical tools;
Animal fur;
Insect and animal bites;
Plant pollen.

Infectious rashes on the body have their own characteristics, which allow doctors to diagnose correct diagnosis only upon visual examination of the patient. The causes of rash formation are the following ailments:

Measles (papular rashes on the scalp, external genitalia, and then damage occurs throughout the entire skin);
Rubella (rash appears as small spots on the face, neck, arms and legs);
Chicken pox (fluid-filled blisters form on the scalp and genitals, then affect the rest of the body);
Scabies (the rash has paired holes that form between the toes);
Scarlet fever (rashes colored bright red color, form on the face, then manifests itself on the elbows, knees, neck);
Herpes (the rash has the form of blisters filled with liquid, affecting different parts of the body depending on the type of virus) and others.

Small rash on the body infectious nature appears in stages. It first appears in one area of the skin and then affects others. Each disease has its own order of spread. Therefore, it is important to inform your doctor about any changes you notice.

Types of allergic rashes

There are several of the most common types of allergic skin rashes:

Features of the differences between allergic and infectious rashes

Allergic rashes do not cause complications in the functioning of the human body. Children may look a little worried. But if the allergen penetrates into the nasal, oral cavity, or gastrointestinal tract, it causes discomfort. Sores on the body of an allergic nature are accompanied by:

The body temperature does not increase, but its appearance may indicate the penetration of infection into the body. Let's say multiple insect bites were found on the body, they were scratched, which led to infection.

Infectious rashes cause enlargement of lymph nodes, disruption of the integrity of skin on the feet and palms, blisters are filled with purulent fluid.

Features of rashes and treatment of rashes on individual parts of the body

There are a colossal number of reasons for the manifestation of allergies on the body. A patient may mistake an infectious disease for a normal skin irritation. And in the absence of proper treatment, a rash on the body can acquire global proportions and develop into chronic illness. It is difficult to independently determine the type of allergic skin rash, so consultation with a dermatologist is necessary.

Rash on back

A rash on the back occurs due to a weakened immune system, deteriorating environmental conditions, or stressful situations. Allergic rashes cause itching, peeling of the skin, and stimulation of the central nervous system. A red rash on the back may indicate urticaria. Additional information You can learn about back acne.

If the rashes appear only on the sides, then there may be a malfunction of the liver. Therefore, internal organs should be diagnosed so that the disease does not reach a serious stage.

Before starting treatment, it is necessary to eliminate contact with the allergen (clothing, food, medication). To get rid of unpleasant symptoms, you should use antihistamines. These include Tavegil, Claritin, Zodak, Zirtek, Suprastin.

If it is difficult to independently determine the cause of an allergic reaction, it is recommended to undergo special tests to identify the allergen. Subsequent treatment is prescribed by the attending physician.

Rash on the face and neck

A rash on the face and neck most often occurs due to the use of low-quality cosmetics or medical supplies, after wearing metal products, exposure to eau de toilette or perfume. To combat rashes, you should identify the irritant and not use it. Doctors recommend using Loratadine, Ketitofen, Diazolin, Suprastin, Cetirizine, Erius as medications. For children younger age Claritin and Fenistil drops should be given. Creams are also prescribed: Advantan, Afloderm, Cinacort, Solcoseryl and Elkom. We also recommend paying attention to.

Allergic dermatitis can form even on those areas of the skin that have not been in contact with the irritant. It is not the skin that reacts to the allergen, but the human immune system.

Rash on the elbow and popliteal cap

Rashes on the elbow and popliteal cap occur due to exposure to external allergens and microbes. Irritants cause itching, discomfort and discomfort. In some cases, the rash is a consequence of complex diseases: eczema, lichen different types, granuloma, psoriasis. In most cases, the rash does not pose a threat to the health of the person or those around him. The irritant should be identified and then the affected areas should be treated herbal decoctions. A decoction of celandine and St. John's wort has a good effect on inflammation of the skin. Wet the affected areas several times a day.

Rash under the armpits and other folds that occurs naturally

A rash under the arms is the result of a disruption in the functioning of internal organs, personal hygiene and stressful situations. It’s as if the body is signaling that it needs help. Before proceeding with the choice of treatment, it is necessary to analyze the situation, whether the rash is a consequence of:

Effects of antiperspirant (the product clogs skin pores for 10 - 12 hours, if not hygiene procedures, then an inflammatory process may occur);
Improperly performed depilation will reveal inflammation;
Use of body care products (shower gels, creams, lotions). They may contain an allergen.
Underwear made from synthetic fabrics (the material does not allow the skin to “breathe”, this provokes a skin reaction);
Consequence of diseases ( diabetes, tuberculosis, obesity, endocrine system disruption, hormonal disruptions, menopause, puberty).

Treatment for armpit rashes is as follows:

Avoid contact with the allergen (possibly following a diet or avoiding the irritant);
Use 3 times a day;
Application of lotions using boric acid;
Use of antihistamines: Suprastin, Claritin, Diazolin.

A rash on the legs and arms is a direct result of skin contact with an irritant.

Rashes on the legs and arms are dangerous because they cause discomfort, and in some cases can interfere with normal movement. Allergies have the following symptoms: the presence of peeling, redness, dry skin, the formation of spots and pimples, and swelling. As treatment, it is recommended to use antihistamines (Tavegil, Suprastin, Loratodin, Astemizole, Cetrin), allergy ointments (Gistan, Sinaflan, Lokoid, Elokom).

Nervous skin rashes

A rash as a result of nervous overexcitation is no less common than allergic rashes. It occurs as a result of increased excitability, higher level anxiety, fatigue, in stressful situations or depression. Treatment combines the use of sedatives medicines, and antihistamines. In this case, it is recommended to use Astemizole, Diazolin, Peritol, Fenkarol. Herbal warm baths (decoction of chamomile, valerian, mint and lemon balm), applying soda lotions (1 tsp per glass of water) will also be effective. In addition, we recommend that you familiarize yourself with the material describing the relationship between.

In most cases nervous rashes on the skin causes hives. Therefore, an integrated approach should be taken in treating rashes.

IN modern life It is difficult for a person to avoid allergens. Various substances that we often use in everyday life act as irritants. Penetrating the skin, they cause a pathological condition. How complex and global it turns out to be can be assessed in an individual medical examination. Having information about the causes and extent of allergies, you can prevent or minimize its spread on the skin.

Skin is the most large organ human and it is not surprising that in the process of diseases occurring inside the body, side effects appear on the skin in the form of various types of rashes. Any symptom requires careful consideration; in this article about skin rashes in adults, we analyze the causes with photos, help you identify the culprit of the rash, and also consider diseases, early symptom which are often skin manifestations.

A rash may indicate:

Immune system problems.
Gastrointestinal diseases.
Allergic reactions.
Problems with nervous system caused by stress.

So what is a skin rash?

It is generally accepted that a rash is caused by changes in the skin and (or) mucous membranes. Changes may include primarily changes in color, texture of the skin surface, peeling, itching in the red area and pain.
The rash can be localized completely different places on the body, for different types rashes exist typical places appearance, for example, rashes associated with allergic reactions most often manifest themselves on the hands and face, while manifestations on the surface of the body are more often associated with infectious diseases.

Remember, scratching the rash is unacceptable in any case, this will lead to even more irritation of the skin and possible education ulcers.

Types of rash

Skin rashes may have different kind, but are always divided into two types:

Primary- occur in areas healthy skin or mucous membranes due to pathological processes in the body.

Secondary– arise at the site of the primary ones for certain reasons (for example, lack of treatment)

By far the most favorable in terms of diagnostic capabilities and subsequent successful therapy are the primary protrusions. All performances vary external signs such as size, shape, content, degree of coloring, grouping, etc.

Let's look at the main types of performances

Spot– Manifested by changes in skin tone or redness. Occurs in diseases such as syphilitic roseola, vitiligo, dermatitis, this type of manifestation also includes birthmarks, freckles.

Blister– Swollen redness with smooth edges, can be of regular or irregular shape, common causes of appearance: urticaria, insect bites, toxicoderma, usually does not require special treatment.

Pustule- a formation filled with pus in the layers of the epidermis, divided by type into superficial and deep. Accompanying diseases such as acne, impetigo, furunculosis, ulcerative pyoderma.

Nodule– can be found in all layers of the skin, externally it looks like a change in the surface of the epidermis with redness and a difference in density from the surrounding tissues, usually ranging in size from 1 to 10 mm. Typical manifestations of the nodule are caused by: psoriasis, several types of lichen, eczema, papillomas, various warts.

Allergy rash

The reason for the constant skin itching and visible rashes on the skin are often allergies, this is quite common occurrence Nowadays, about 70 percent of people are somehow susceptible to or have experienced allergic reactions.

What is an allergy? This is an aggravated reaction of the human immune system to an allergen that has entered the body, while in the process of getting rid of the presence of the allergen, a person’s blood vessels dilate and histamine is produced in large quantities, also, redness, inflammation, swelling, and itching are almost always added to the above symptoms.

Attention! In the event of an acute allergic reaction with the formation of edema, the patient should immediately call an ambulance!

Allergic dermatitis also often manifests itself - when exposed to an allergen, a rash area forms at the point of contact, for example, when reacting to clothing - rashes in the waist, back and those places on the body where clothing fits most tightly to the skin, or when reacting to perfume or deodorant – in the area of greatest contact with the substance (often under the arms)

At mild form Allergic reaction symptoms resemble those of a cold: runny nose, possibly increased salivation and watery eyes. If you experience symptoms such as dizziness, tachycardia, convulsions and nausea, this may indicate a severe allergic reaction in which there is a risk of developing anaphylactic shock, you must consult a doctor immediately.

Allergies can be caused by:

Pet hair
Plant pollen in summer or autumn period of the year
Medications
Food products (chocolate, milk, citrus fruits, etc.)
Various nutritional supplements
Substances contained in perfumes or household chemicals
Substances that make up wardrobe items (fabric, metals, dyes)

Rash due to infectious diseases

Rashes in infectious diseases are often characterized by stages of appearance, first it appears in one place, then in another, also for each infection there are typical places for rashes, a specific shape and size, it is important to remember all the details and, when interviewing, report all this information to the doctor.

Below we look at rashes associated with various infectious diseases:

Rubella– in the initial period of the disease small rash appears on the face and neck, then within 2 to 6 hours the rash spreads throughout the body. Usually appears as round or oval redness ranging from 2 to 10 mm in size. Remains on the skin for up to 72 hours, then disappears without visible traces. If you find yourself with a similar rash, you need to consult and examine a doctor, since similar rashes are symptoms of many infectious diseases. We also recall that rubella poses a particular danger to pregnant women, since if the mother is ill, the infection can harm the fetus.

Measles– measles disease usually manifests itself with catarrhal manifestations. The rash appears after 2-7 days. The primary places of protrusion are on the skin of the nose and behind ears, then within 24 hours it spreads to the skin of the chest, face, then the arms and neck also become covered with rashes. After 72 hours, the rash also covers the legs; the rash is most often intense and confluent. After the active phase of the disease, the rash changes color and forms something like pigment spots.

Chicken pox– with the onset of the disease it manifests itself as red spots, then bubbles with a red ring and liquid inside appear, similar in appearance to dewdrops. After two days outer surface the bubble subsides and becomes less elastic. Subsequently, the blisters become coarser, crust over and disappear within seven days without leaving any visible traces.

Scarlet fever- Rashes with scarlet fever appear 24 hours after infection, the areas of active manifestations are the back, groin, elbow and knee bends, and armpit skin. Then inflammation appears on the skin, sometimes there is a slight blue discoloration in the places where roseola forms. The face with scarlet fever is usually not affected by a rash.

Let's look at the reasons with photos:

Rashes caused by infection:

Herpes– a scattering of small transparent bubbles forms on the surface of the skin of the face and lips correct form, then within 72 hours the bubbles become cloudy, dry out with the formation of darkish or gray-yellow crusts.

Warts– the skin of the extremities is usually affected; they look like dense, rough formations irregular shape grayish color.

Warts on the hand

Syphilis– the appearance of rashes generally always accompanies secondary syphilis; the rash is almost always varied in the visual signs of the elements and their number on the patient’s skin. Typically, a syphilis rash is not accompanied by any additional sensations or unpleasant effects, after disappearance there are no traces left on the skin. Secondary syphilis is accompanied by spotty rashes, which are characterized by a symmetrical arrangement, brightness and abundance. After 60 days, the rash usually goes away, after some time the rash appears again, not as abundant, more dull in color, localized in places of skin trauma, between the buttock muscles, in the groin, on the shoulders and on the chest.

Candidiasis– (yeast diaper rash) the usual places of manifestation are in the area of folds of the skin, folds of the abdomen, most often affects people with overweight, the first stage of the disease is accompanied by small blisters and pustules, which, when bursting, transform into wet erosions of a reddish-brownish color, which tend to merge. Cracks and accumulations of whitish, mushy tissue form on the surface of the patient's skin.

Pityriasis rosea– at the beginning of the disease, a red-pinkish spot appears on the skin of the chest and/or back with peeling in the central part, after which a spot-like rash of usually symmetrical shape forms on other parts of the body.

Shingles– manifests itself in the initial period as a group of blisters up to 50 mm, localized on one side of the chest, abdomen, head or shoulder; when they appear on the affected area, sensitivity worsens, accompanied by pain; after the blisters disappear, areas of hyperpigmentation and/or scars remain on the skin.

Lichen planus- usually the rash appears in the form of clusters of nodules and forms lines, rings or arcs on the skin with equidistant elements. Common sites of injury: trunk, inner surface limbs, genitals. The disease causes itching.

Molluscum contagiosum – shiny bubbles with smooth walls, translucent with a typical inclusion of pinkish, reddish or yellow flowers, with sizes from 2 to 10mm. Upon palpation, white mushy contents are released.

Rubrophytia– a disease of a fungal nature, in one hundred percent of cases a person’s feet are affected, initial stage This is keratinization and peeling of the skin between the 3rd and 4th toes; during the course of the disease, manifestations in the form of erosion and blisters are possible; if the disease develops, the entire surface of the foot is affected.

Athlete's inguinal– skin lesions are usually in the area of folds in the groin (locations may vary). In the initial stage of the disease, spots of a reddish hue of regular shape and with an unchanged surface appear. As the disease progresses, the heel usually merges and forms a lesion on the skin with scalloped borders. The main area of the lesion is covered with crusts, erosions and scales.

Acne– can appear all over the body, but more often occur on the face, usually during puberty, and are divided into comedones (clogged pores), papules, pustules, and cysts. In case of illiterate treatment and neglected form It is possible that scars may appear on the skin after acne is treated.

Vitiligo– white spots of various shapes and sizes become noticeable on the skin; the spots may merge into one.

Solar keratosis– formed due to excessive exposure sun rays on unprotected skin, looks first as redness then as a keratinized dry crust, affects mainly older people, with untimely treatment carcinoma (skin cancer) may develop

Psoriasis– characterized by the appearance large quantity bright pink papules covered with scales, the number of papules increases as the disease progresses, they merge into large plaques, most often the rash at the initial stage appears in the area of the bends of the elbows and legs, as well as on the head.

Psoriasis

Any changes in skin condition are the result of one disease or another. The appearance of rashes on the skin may indicate damage to the body by infectious agents or be a manifestation of an allergic reaction provoked by its contact with a potential irritant. In addition, the occurrence of a rash often represents specific symptom, characteristic of damage to internal organs, in particular the liver, endocrine glands or intestines.

As is known, skin diseases are often accompanied by peeling, the formation of crusts and areas of redness, and also occur with itching, burning, and the development of weeping areas and bleeding surfaces. If such disorders occur, the patient should immediately contact a specialist, especially if the rash on the body itches and continues to progress over time. Itchy skin is dangerous because it increases the likelihood of developing large-scale excoriation (scratching) with its further infection and transformation into widespread purulent process. What to do if a red rash on an adult’s body is very itchy, how to treat this condition?

Allergic diseases

A red rash on the body of an adult is most often a symptom of an allergy. This specific reaction the body can be provoked by numerous allergens that a person encounters in Everyday life almost every day. Allergic rashes on the skin often occur after consuming certain foods, medications, or contact with household chemicals, animal hair, metals. Allergies can occur throughout the body or where the skin comes into contact with an irritant. It has the appearance of a red rash located on the swollen surface, it is very itchy and begins to peel off as it develops.

Common form skin allergies– urticaria. It appears as red blisters of varying sizes and with unclear contours, located on the elevated surface of the skin. Such a rash itches and is prone to generalization of the pathological process, provided that irritant, which provoked the condition, was not eliminated in time. Urticaria may occur against the background allergic conjunctivitis or without it.

Fungal infections and lichen

If a rash appears, the cause may be infection of the skin with pathogens of fungal diseases and lichens. These diseases are not characterized by a specific appearance rashes. In the majority clinical cases Red areas (spots) and itching on the skin appear on the body. Over time, in places of infection, a similar rash on the body of an adult becomes covered with profuse peeling, and sometimes an unpleasant odor emanates from it.

Fungal infections and lichens are localized mainly in the natural folds of the body, under the mammary glands and on the neck. They spread quickly and without adequate treatment may become chronic or generalized. Such diseases are almost never accompanied by an increase in general temperature bodies, although there are conflicting cases.

Bacterial infections

If a red rash on the body of an adult itches and gradually increases in size, and also burns and becomes covered with purulent crusts, then you should think about the development of a pathological process provoked by bacteria. Moreover, the appearance of such a rash largely depends on the nature of the pathogen. As a rule, all bacterial skin infections are accompanied by fever, in which the body temperature can reach 40 degrees. Such pustular rashes quickly mature and burst with the release of thick purulent exudate yellow color.

A purulent rash on the skin and itching are characteristic of furunculosis, streptococcal pyoderma, and the like. It is sometimes associated with herpetic eruptions or may result from infection of the skin surface after scratching due to an itchy sensation caused by another disease of the epidermal tissues.

Rash due to intestinal infections

A number of diseases intestinal tract manifests itself skin rash on the body of an adult that itches or is not accompanied by itching sensations. For example, with typhoid fever, red dots or spots appear on the body, which are called roseola. Such rashes are inflammatory nature and have a mesh surface, they disappear when pressed and reappear after it. Roseola rash is one of the the most important symptoms typhus, the determination of which is important to confirm the diagnosis.

With other intestinal ailments, skin rashes and itching are not so pronounced. Sometimes in patients suffering from dysbiosis, intestinal infections or chronic colitis Small red dots may appear on the body, which go away on their own without treatment after the manifestations of the underlying disease are eliminated.
