title: Hidradenitis suppurativa and squamous cell carcinoma.
abstract: BACKGROUND
  Hidradenitis suppurativa is a recurrent, chronic inflammatory disease with complications such as abscesses and sinus tract formations, fistulization, and scarring. Squamous cell carcinoma is rare, and is the most serious complication.
  
  
  OBJECTIVE
  To present the evolution of squamous cell carcinoma in long-term hidradenitis suppurativa.
  
  
  METHODS
  Case report and literature review.
  
  
  CONCLUSIONS
  Many conservative therapies have no or minimal effect in perineal hidradenitis suppurativa. Therefore surgical excision must be considered in the early stages of the disease at this region to prevent further complications.
