Purpura Annulare Telangiectatic

Purpura anularis teleangiectatica is a rare skin disease of unknown etiology, characterized by the appearance of ring-shaped purple rashes with telangiectasias on the skin.

Other names for this disease: Majocchi disease, follicular annular telangiectasia.

The reasons for the development of purpura annulare telangiectatica are not fully understood. It is assumed that the underlying cause is damage to small vessels of the dermis, leading to their expansion (telangiectasia) and ruptures with the subsequent formation of hemorrhages.

Clinically manifested by the appearance on the skin of ring-shaped rashes of a purple-bluish color ranging in size from 1 to 5 cm. Telangiectasias are noted in the center of the lesions. Characterized by a tendency to peripheral growth and fusion of foci with the formation of garland-like figures. The extensor surfaces of the extremities are most often affected. There is no itching or other subjective sensations. The course is chronic, relapsing.

The diagnosis is made based on the clinical picture. Histologically - dilation and tortuosity of the vessels of the papillary dermis, perivascular edema, hemorrhages.

Treatment is usually ineffective. Antihistamines, vitamins B and C, and external corticosteroids are used. In severe cases, systemic glucocorticoids and platelet aggregation inhibitors are prescribed.

The prognosis is generally favorable, but frequent relapses are possible.

Purpura annulare telangiectaticis is a rare skin condition that is characterized by the appearance of ring-like lumps on the skin, usually on the arms and legs. The name "purpura annulare" comes from the Latin word "purus", which means "white and also the color purple" and the Latin word "anulus", which means "ring". Telangiectatic fibers or umbilical cord fibers become more visible in the ring-like seal of the skin.

The disease most often affects people between 30 and 60 years of age, but can occur in people of any age. The disease can be inherited from one of the parents, but there is no proven genetic link
