Seven subungual epidermoid carcinomas (CA) and 4 subungual keratoacanthomas (KA) of the hand are reported, and the literature is reviewed. Subungual CA is a very slow‐growing tumor that masquerades for years as a chronic infection, whereas subungual KA grows rapidly, is more destructive locally, and clinically appears to be a tumor of some type. The average age of patients with CA was 64, but only 49 for patients with KA. About two thirds of the CA demonstrated roentgenographic evidence of osseous involvement, whereas all cases of KA produced pressure erosion of the distal phalanges. Neither tumor metastasizes. KA might spontaneously resolve if permitted to run its natural course. The treatment of choice for CA is probably a conservative amputation and for KA, curettage.
