title: Is cutaneous leishmaniasis a risk factor for basal cell carcinoma?
abstract: BACKGROUND
  Basal cell carcinoma (BCC) is the most common epithelial neoplasm of skin. Risk factors for the development of BCC include intermittent intense sun exposure, radiation therapy, family history of BCC, immune suppression and fair complexion, especially red hair. It can originate in scars like small pox, vaccination, chicken pox or surgical scars.
  
  
  CONCLUSIONS
  We present a case of basal cell carcinoma arising in a leishmania scar on the nose, sixty years after the primary lesion. Although rare, BCC's have arisen in leishmania scars. Thus the possibility of basal cell carcinoma should be considered while dealing with such patients. Even though a causal relationship, if any, cannot be ascertained at present.
