Subungual basal cell carcinoma.
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.
