Diseases of the skin and subcutaneous tissue (dermatology)

Erythema annulare centrifugal Darier: causes, symptoms, diagnosis, treatment

The causes and pathogenesis of erythema annulare centrifugum Dariera are not fully understood. Apparently, the disease should be considered as a reactive process. There is a connection between erythema and fungal infection of the feet, candidiasis, and drug intolerance. In addition, there are cases of the onset of the disease in patients with leukemia and systemic lupus erythematosus.

Climacteric keratoderma: causes, symptoms, diagnosis, treatment

Currently, many dermatologists consider keratoderma climacterica as part of the climacteric syndrome. The occurrence of the disease is associated with hypofunction of the ovaries (fading of the function of the sex glands) and the thyroid gland. This dermatosis affects 15-20% of women.

Pathomimia (Munchausen syndrome): causes, symptoms, diagnosis, treatment

The presence of erosion, ulcers or scratches located on open, hand-accessible areas of the gel is noted. Skin damage can be disfiguring. People with altered psyche, depressed mood, and difficulty adapting to the surrounding conditions are ill.

Follicular mucinosis

The basis of follicular mucinosis is degenerative changes in the hair follicle and sebaceous glands with the destruction of their structure and the deposition of glucosaminoglycans (mucin).

Cutaneous manifestations in Cushing's Syndrome: causes, symptoms, diagnosis, treatment

Cushing's syndrome occurs when the level of glucocorticoids in the blood increases. Endogenous Cushing's syndrome is caused by excessive production of cortisol by the adrenal cortex. Excessive production of ACTH is observed in the following conditions: dysfunction of the hypothalamic-pituitary system; micro- and macroadenomas of the pituitary gland secreting ACTH

Lipoid necrobiosis: causes, symptoms, diagnosis, treatment

Necrobiosis lipoidica (synonyms: lipoid diabetic necrobiosis, atrophic macular lipoid dermatitis) occurs in 4% of patients with diabetes mellitus.

Anetoderma: causes, symptoms, diagnosis, treatment

Anetoderma (synonym: macular cutaneous atrophy) is a type of skin atrophy characterized by the absence of elastic tissue.

Skin xanthomas: causes, symptoms, diagnosis, treatment

Skin xanthomas, in particular multiple tuberous xanthomas, are one of the manifestations of impaired lipid metabolism. An increase in the level of triglycerides and cholesterol in the blood plasma has been revealed due to a disorder in the formation, transport and breakdown of lipoproteins. Clinically, eruptive, tuberous, tendinous and flat xanthomas are distinguished.

Pellagra

Pellagra (pelle agra - rough, rough) is a disease that occurs as a result of a deficiency in the body of nicotinamide, tryptophan, and vitamins belonging to group B. If the clinical manifestations of the disease were first described by the Spanish doctor G. Casal (1735), then the Italian doctor F. Frappoli called the disease pellagra.

Amyloidosis of the skin

Amyloidosis is a metabolic disorder in which amyloid is deposited in the body's tissues. Research has shown that amyloid is a glycoprotein of protein nature. The deposition of this protein leads to disruption of tissue and organ function.
