Squamous cell carcinoma arising from perineal lesion in a familial case of Hidradenitis suppurativa

Abstract

Hidradenitis suppurativa (HS) is a chronic dermatologic disorder characterised by multiple vesiculopustular cutaneous lesions in skin. It sometimes express autosomal dominant mode of inheritance. In some patients, it can give rise to squamous cell carcinoma of skin. Unlike the usual marjolin's ulcer which develops in chronic scars, this disease carries a grave prognosis with high recurrence rate and mortality. Here we are reporting the case of a 40-year-old gentle man with hidradenitis suppurativa, who presented with squamous cell carcinoma in the perianal region, and had multiple family members affected with HS. A short history and review of literature are discussed. Squamous cell carcinoma arising from HS is a major therapeutic challenge. This malignancy carries very high rates of recurrence and mortality. Careful surveillance of the lesions of HS, especially occurring in perineal region is very important to diagnose secondary malignancies. Similarly, meticulous surgical excision with careful resection of all sinus tracks and frozen section examination of margins are very important to eradicate the disease. © 2009 Blackwell Publishing Ltd and Medicalhelplines.com Inc.
