title: Squamous cell carcinoma occurring in hidradenitis suppurativa.
abstract: A patient is described who had severe hidradenitis suppurativa of the perineum for three years. Excision of the involved area demonstrated a well-defined squamous cell carcinoma. A review of the literature shows only 12 reported cases of squamous cell carcinoma occurring in patients with hidradenitis suppurativa; most patients developing cancer in chronic inflammatory lesions have had longstanding disease. In this case there was a short interval between disease onset and the occurrence of a squamous cell carcinoma.
