Much has been written on epithelioma of the extremities, especially on epithelioma of the hand (Fox,1 Tourneux2). But insufficient attention has been given to the incidence of the basal cell variety in these regions. There are no records in the surgical or dermatologic literature devoted entirely to this form of cancer of the skin as involving these locations. Moreover, it is the impression among dermatologists that primary basal cell epithelioma of an extremity is uncommon. These facts may explain why the clinical diagnosis of primary basal cell epithelioma of the extremities is rarely ventured. Even when proved by histologic observations, such a diagnosis is accepted with hesitancy on the part of the clinician. This discrepancy between the clinical and the laboratory diagnosis arises so frequently that its causes warrant investigation.
