Hidradenitis Suppurativa

A 36-year-old woman has recurrent boils under both arms and in the groin. They flare premenstrually, causing pain, suppuration, and an offensive odor. Scarring has developed in the groin area, and chronically draining sinus tracts are interspersed with normal skin. Treatment with short courses of antibiotics or with incision and drainage has had no apparent effect, and she has become socially isolated because of embarrassment about her condition. How would you manage this case?
