Hidradenitis suppurativa (HS) is an inflammatory disorder of the apocrine gland-bearing regions of the skin, which presents with recurrent painful nodules and suppuration. The primary nodules may develop into abscesses and tunnels (si-nus tracts) and scarring (1). Patients often go years without a diagnosis, resulting in repeated courses of ineffective medical treatments, such as dicloxacillin, and surgical procedures, such as attempted incision and drainage. It may be speculated that, despite clear clinical diagnostic criteria for HS, for some less-experienced doctors, differential diagnosis may still not be well-established.
