Diseases of the skin and subcutaneous tissue (dermatology)

Kaposi's pseudosarcoma

Pseudosarcoma of Kaposi is a chronic vascular disease of the skin of the lower extremities, clinically very similar to Kaposi's sarcoma, developing as a result of venous insufficiency (Mali type) or insufficiency of arteriovenous anastomoses (Blufarb-Stewart type).

Atrophic malignant papulosis: causes, symptoms, diagnosis, treatment

Papulosis maligna atrophica (syn.: lethal cutaneous-intestinal syndrome, disseminated cutaneous-intestinal thromboangiitis of Kellmeyer, Degos disease) is a rare disease, the symptoms of which include lesions of the skin and internal organs (mainly the small intestine), caused by endothrombovasculitis, probably of autoimmune origin.

Wegener's granulomatosis: causes, symptoms, diagnosis, treatment

Wegener's granulomatosis is a disease characterized by necrotizing granulomatous inflammation of small and medium vessels with predominant damage to the upper respiratory tract, lungs and kidneys.

Facial granuloma: causes, symptoms, diagnosis, treatment

Facial granuloma (syn.: eosinophilic facial granuloma) is a rare disease of unclear etiology. Trauma, immune and allergic reactions, and increased sensitivity to light are assumed to play a role in the development of facial granuloma.

Erythema persistent elevated: causes, symptoms, diagnosis, treatment

Erythema persistente elevated is considered a localized form of leukocytoclastic vasculitis, although the final location of this disease has not been determined.

Purpura pigmentosa progressive chronic: causes, symptoms, diagnosis, treatment

Purpura pigmentosa chronica (syn.: purpuric-pigmented dermatosis, hemosiderosis). Depending on the difference in the clinical picture or the mechanism of occurrence, purpuric-pigmented dermatoses in the literature have a large number of forms.

Nodular panarteritis: causes, symptoms, diagnosis, treatment

Nodular panarteritis (syn.: nodular panvasculitis, nodular periarteritis, Kussmaul-Meyer disease, necrotizing angiitis) is a systemic disease caused by vascular damage, probably of autoimmune genesis, which is confirmed by the detection of immune complexes in the walls of affected vessels.
