Diseases of the skin and subcutaneous tissue (dermatology)

Furunkul

Furuncle is a purulent-necrotic inflammation of the hair follicle and surrounding tissues. The etiology is diverse, mainly determined by staphylococcus or mixed microflora. The reasons for the introduction of the infection are: rubbing of the skin, irritation with chemicals, increased function of sweat and sebaceous glands, microtrauma, metabolic diseases.

Pyoderma

Piodermaids (Greek ruon-pus, derma-skin) - pustular skin diseases caused by pyogenic microorganisms, mainly staphylococci, streptococci, less often - other microorganisms.

Pigmented nevus: causes, symptoms, diagnosis, treatment

At the heart of the pigmentless nevus is a decrease in the activity of melanocytes. The amount of the latter in the skin is normal. In the cytoplasm of melanocytes, the amount of melanosomes is also normal, whereas in keratinocytes the amount of melanosomes is reduced.

Vitiligo

According to various studies, in the world the average prevalence of vitiligo among the population is about 1%. The causes and pathogenesis of vitiligo is still unknown. Currently, the most recognized theories of the emergence of vitiligo are neurogenic, endocrine and immune theories, as well as the theory of self-destruction of melanocytes.

Sarcoidosis: causes, symptoms, diagnosis, treatment

Sarcoidosis (synonyms: Benjet-Beck-Shauman disease, benign sarcoidosis, Beck's disease) is a systemic disease of unknown etiology that affects a variety of organs and tissues, the pathomorphological basis of which is epithelioid-cell granuloma without evidence of caseous necrosis. The disease was first described by the Norwegian dermatologist Bek (1899).

Spontaneous panniculitis: causes, symptoms, diagnosis, treatment

The causes and pathogenesis of spontaneous is not fully understood. Of great importance are the transferred infections, trauma, drug intolerance, pancreatic lesions, etc. A certain role is played by the processes of lipid peroxidation.

Chronic ulcerative vegetative pyoderma: causes, symptoms, diagnosis, treatment

Chronic ulcerative vegetative pyoderma is a deep form of pyoderma caused by streptococcal and staphylococcal infections. It occurs in people of any age. Development of the disease is promoted by severe immunodeficient conditions, leading to a decrease in the body's defenses, and a violation of the normal functional state of the skin.

Gangrene of the penis and scrotum: causes, symptoms, diagnosis, treatment

It is believed that the gangrene of the penis and scrotum is caused by Staphylococcus aureus, streptococcus, less often - Proteus. In the pathogenesis of the disease, an important role is played by sensitization to pathogens and their decay products, the development of allergies, the involvement of skin vessels, the development of ischemia and necrosis.

Shankriform pyoderma: causes, symptoms, diagnosis, treatment

Shankriform pyoderma is a bacterial infection of the skin resembling a syphilitic chancroid. The causative agent of the disease are staphylococci and streptococci. The disease develops with a decrease in the defenses of the body (the state of immunodeficiency) and the irrational therapy of the underlying disease (scabies, etc.)

Skin changes in erysipelas: causes, symptoms, diagnosis, treatment

Erysipelas - an acute inflammation of the skin. It occurs at any age, but elderly people are more often ill. The causative agent of the disease is Staphylococcus aureus, group A streptococcus (Streptococcus pyogenus). Gateway infection is any damage to the skin and mucous membranes.
