title: Unusual location of vulvar basal cell carcinoma.
abstract: BACKGROUND
  Basal cell carcinoma (BCC) is a rare tumor of the vulva; it accounts for approximately 2% to 4% of vulvar cancer.
  
  
  METHODS
  A 73-year-old woman was referred because of a 2-cm ulcerative lesion on her perineum, near the anus. Punch biopsy showed BCC. She underwent wide local excision of tumor without any damage to the anal sphincter. The postoperative period was uneventful and the cosmetic results were good.
  
  
  CONCLUSIONS
  BCC most commonly occurs in sun-exposed areas, but it may be seen in rare locations, such as in perineum. In our case, chronic irritation secondary to long-term chronic candidiasis in the presence of diabetes mellitus may have been contributory to the development of vulvar BCC.
