Basal cell carcinoma presenting late in a shotgun scar.

The development of a basal cell carcinoma (BCC) as a late complication of a shotgun injury is a rare clinical entity. We report the case of a 68-year-old Caucasian man who developed a BCC at the site of a scar from a shotgun pellet entry wound that was sustained 14 years previously. We emphasize the importance of excluding malignancy in a non-healing lesion and discuss the possible etiologic factors in the development of a BCC at the site of previous trauma.
