Basal cell carcinomas (BCC) of the foot are rare. A review of the English literature found only 23 cases of BCC reported in the foot, none of which involved the nail unit. The nail unit, which is composed of the nail bed and nail-folds, is an exceedingly atypical site for basal cell carcinomas. A case of BCC of the proximal nail fold of the hallux which was treated with Mohs Micrographic Surgery (MMS) is presented.16–21
