Basal cell carcinoma developing on a burn scar.

Basal cell carcinoma occurring on a burn scar is quite care. However, when it does occur, it is usually seen on sites exposed to the sun or on sites with embryological closure lines. A case of basal cell carcinoma which developed on a burn scar on the trunk is described. The injury was from a flame burn which occurred more than 50 years ago. No mechanical irritation had occurred on the lesion since then.
