Skin rash

A rash on the skin can indicate pathological changes in the functioning of internal organs, manifestations of an infectious disease or an allergic reaction, and is the first sign to visit a doctor. A rash is a pathological formation on the skin with a variety of morphological features. It is divided into primary and secondary.
Types of rash
A papule is a dense nodule rising above the skin, without a cavity, having both an inflammatory and non-inflammatory character. Its dimensions range from 1 millimeter to 3 centimeters. They can be located both on the upper layers of the dermis and at depth.
A vesicle is a bubble filled with a clear liquid, sometimes with blood. They can have one or more chambers, located on the upper layers of the epidermis, slightly rising above the skin. If the size of the vesicle is up to 1 cm, the rash is called a vesicle. If the vesicle size is more than one centimeter, then such a rash is called blisters. When the vesicle is opened, ulcers and erosions remain.
A pustule is a vesicle similar in structure, but instead of a clear liquid, it contains pus. There are pustules located closer to the surface, they are called flyctenes and located in the lower layers of the epidermis and dermis, they are called ecthymes. Flycten is characterized by redness in the form of a rim, and for the ecthyma there are large affected borders. A follicular pustule is called if it forms around a hair follicle.
A tubercle is a rash located in the deep layers of the skin, after the tubercle is restored, scar tissue or atrophy of the affected area forms. The dimensions can vary from 50 millimeters to one centimeter.
A blister is a pink formation that has no cavity and no clear boundaries. The cause is swelling of the papillary layer of the skin. It often causes itching and disappears within ten hours.
A node is a formation that does not have a cavity, but with obvious signs of infiltration, located in the deep layers of the dermis, has a relatively large size with or without inflammation. On palpation, there may be a soft or hard structure.
A spot is a change in the color of a certain area of the skin, with clear boundaries or not at all. The spot does not rise above the skin.
Roseola is a spot with a red-pink hue up to 5 millimeters in size, without clear shapes and boundaries. A characteristic feature is the disappearance when pressed on the skin, where the roseola is located.
Hemorrhage is subcutaneous bleeding of various localizations that do not have clear boundaries and sizes.
If the rashes described above appear, you should consult a dermatologist who will identify the cause, prescribe the right treatment and tell you about the necessary changes in diet and lifestyle.
