Hidradenitis suppurativa is a chronic inflammatory disease that usually affects areas of the skin with a high density of apocrine glands (axillae, groin, perianal and perineal regions, submammary area, etc). It usually appears in women during puberty. The etiology of the disease is unknown, although it is thought to be a primary defect of the hair follicle. When diagnosing hidradenitis suppurativa, a number of genetic and hormonal predisposing factors should be considered alongside other putative triggers, such as obesity, smoking, and tight clothing. Diagnosis is essentially clinical and it is important to bear in mind the possible complications associated with the disease, such as the development of tumors. Management of the disease includes general measures (antiseptic soaps, warm baths, etc), pharmacological therapy (topical, intralesional, and systemic), surgery (direct closure, second-intention healing, grafts, flaps, etc), and other measures (carbon dioxide laser, radiation therapy, etc). It is important that the disease be diagnosed and treated as soon as possible given the potential physical and psychological problems that it can generate.
