title: Subungual basal cell carcinoma.
abstract: Subungual basal cell carcinoma is rare. Only eight cases, all involving fingers, are on record. Two additional cases are reported in this paper. One lesion was on a toe, the only one observed at this site. As the lesion may simulate a number of conditions, most of which are benign, the importance of obtaining a biopsy from a recalcitrant lesion of the nail organ cannot be overemphasized.
