HYDRADENITIS - purulent inflammation of the sweat glands, often axillary.
The first sign of the disease is a small, dense, painful, gradually increasing nodule in the thickness of the skin and subcutaneous tissue. Initially, this nodule is covered with unchanged skin, and then its surface becomes uneven, purple-red. When several sweat glands are involved in the process, multiple infiltrates with an uneven tuberous surface develop, with a purulent fusion of which an abscess forms. In contrast to the boil with hydradenitis, there is no necrotic core.
Conservative treatment at the stage of infiltration (rest, dry heat, UHF-therapy, sollux, ultraviolet radiation, antibiotics). Surgical intervention (opening an abscess) is indicated for abscess formation of hydradenitis. Further treatment is carried out according to the general rules for the treatment of purulent wounds. With a persistent recurrent course of hydradenitis, specific immunotherapy is indicated (the introduction of staphylococcal toxoid, staphylactic vaccine, auto-vaccine) in combination with restorative agents.
Prognosis is usually favorable, but relapses are possible.
Prevention is about personal hygiene. Persons prone to hydradenitis are advised to treat the skin, in particular in the axillary areas, with a 10% solution of camphor alcohol, and also periodically conduct ultraviolet irradiation of the skin of these areas.
