Diseases of the skin and subcutaneous tissue (dermatology)

Skin lipoma: causes, symptoms, diagnosis, treatment

Lipoma of the skin is a benign tumor consisting of normal fatty tissue (lipocytes). Many lipomas have a connective capsule. Single or multiple lipomas are usually located on the abdomen, back, and limbs. They are soft to the touch, painless, mobile, the color of normal skin, with a diameter of 1 cm to 10 cm.

Lymphangioma of the skin: causes, symptoms, diagnosis, treatment

Lymphangioma of the skin is a benign tumor of the lymphatic vessels. Lymphangioma exists from birth or develops in childhood.

Hemangioma of the skin

Hemangioma of the skin is a benign vascular tumor. In most cases, hemangioma of the skin tumor develops from birth as a result of proliferation of blood vessels.

Nevi: causes, symptoms, diagnosis, treatment

The basis of the nevus may be autoimmune disorders, i.e. the appearance of cytotoxic antibodies in the blood and the action of cytotoxic lymphocytes. In the focus of depigmentation, a decrease in the melanin content in melanocytes and the disappearance of the melanocytes themselves from the epidermis are noted.

Lymphomatoid papulosis: causes, symptoms, diagnosis, treatment

The causes and pathogenesis of lymphomatoid papulosis remain unknown. Many scientists consider lymphomatoid papulosis as a nodular form of skin lymphoma with slow tumor progression. The disease is observed in young and middle-aged people, more often in men.

Leukemides of the skin (skin leukemia)

Skin leukemias (synonyms: skin leukemia, hemodermia) are symptoms of leukemia and appear in its terminal stage. However, sometimes skin signs are the initial symptoms of leukemia, when other signs (changes in blood, lymph nodes and bone marrow) are still absent.

Jessner-Kanof lymphocytic infiltration: causes, symptoms, diagnosis, treatment

Jessner-Kanof lymphocytic infiltration was first described in 1953 by M. Jessner, NB Kanof. The causes and pathogenesis of the dermatosis have not been fully studied.

Benign lymphoplasia of the skin: causes, symptoms, diagnosis, treatment

Benign lymphoplasia can develop at any age, both in men and women. The clinical picture of the disease is characterized by the appearance of nodules, plaques or infiltrative-tumor elements located mainly on the skin of the face, mammary glands, genitals, armpits.

Kaposi's sarcoma

Kaposi's sarcoma (synonyms: idiopathic multiple hemorrhagic sarcoma, Kaposi's angiomatosis, Kaposi's hemangiosarcoma) is a multifocal malignant tumor of vascular origin affecting the skin and mucous organs.

B-cell lymphomas of the skin: causes, symptoms, diagnosis, treatment

As with cutaneous T-cell lymphomas, cutaneous B-cell lymphomas are caused by the proliferation of abnormal B lymphocytes.
