Diseases of the skin and subcutaneous tissue (dermatology)

Actinic elastosis (elastoidosis): causes, symptoms, diagnosis, treatment

Actinic elastosis (elastoidosis) occurs with prolonged exposure to ultraviolet rays, usually observed in old age (senile elastosis).

Carbohydrate dystrophies: causes, symptoms, diagnosis, treatment

Carbohydrate dystrophies can be parenchymatous and mesenchymal. Carbohydrates found in cells and tissues are identified using histochemical research methods. They are divided into polysaccharides and glucoproteins.

Lipidoses: causes, symptoms, diagnosis, treatment

Lipidoses are storage diseases (thesaurismoses), almost always occur with damage to the central nervous system, so they are called neurolipidoses. Skin manifestations are one of the main symptoms only in diffuse angiokeratoma of Fabry (glycosphingolipidosis), in other forms they occur infrequently, possibly due to early death.

Lipid metabolism disorders: causes, symptoms, diagnosis, treatment

Hyperlipidemia is found in 10-20% of children and 40-60% of adults. It can be primary, genetically determined, or develop secondarily due to dietary disorders, various diseases leading to metabolic disorders (insulin-dependent diabetes, chronic pancreatitis, alcoholism, liver cirrhosis, nephrosis, dysglobulinemia, etc.).

Mesenchymal dysproteinoses of the skin: causes, symptoms, diagnosis, treatment

In mesenchymal dysproteinoses, protein metabolism is disrupted in the connective tissue of the dermis and vessel walls. Metabolic products accumulate, which can enter with blood or lymph or are formed as a result of incorrect synthesis or disorganization of the main substance of the dermis and its fibrous substances.

Fox-Fordyce disease: causes, symptoms, diagnosis, treatment

Fox-Fordyce disease usually develops in women of young or middle age, but can also occur during menopause and in children in the post-pubertal period.

Carbuncle: causes, symptoms, diagnosis, treatment

Carbuncle is an acute, purulent-necrotic inflammation of several hair follicles, the dermis itself and the underlying tissue with the formation of an extensive infiltrate, necrosis. The process has a phlegmonous character and tends to spread.

Ostiofolliculitis and folliculitis

Ostiofolliculitis or staphylococcal impetigo (syn.: Bockhard's impetigo) is an acute inflammation of the mouth of the hair follicle caused by staphylococcus. Single or multiple lesions appear on the skin of hairy areas, most often the face and head, located at the mouths of hair follicles.

Bovenoid papulosis: causes, symptoms, diagnosis, treatment

Bowenoid papulosis is a combination of intraepithelial neoplasia and human papillomavirus infection. It manifests itself as multiple rashes in the genital area of a reddish-brown or bluish color.

Lewandowsky-Lutz epidermodysplasia verruciformis

Epidermodysplasia verruciformis Lewandowsky-Lutz (syn. verrucosis generalisata) is a rare disease, in some cases familial. Autosomal recessive or X-linked inheritance is assumed.
