title: [Perianal basal cell carcinoma].
abstract: BACKGROUND
  The perianal localisation of a basal cell carcinoma is exceptional. Its long term progression and the modalities for its treatment should be known.
  
  
  METHODS
  A 66 Year-old man was referred for a non-regressive haemorrhoidal thrombosis. He presented with a painless but hemorrhagic lesion of the anal-cutaneous junction that had not progressed much over 5 Years but which did not heal. Following exeresis and biopsy, the anatomopathological exploration concluded in an ulcerous-nodular basal cell carcinoma.
  
  
  CONCLUSIONS
  The treatment of perianal basal cell carcinomas consists in the local exeresis of the tumour. Of good prognosis, the possibility of a local relapse however requires strict follow-up.
