BASAL CELL EPITHELIOMAS WITH EXCESSIVE PIGMENT FORMATION

Abstract
Basal cell epithelioma is undoubtedly the most common variety of cancer involving the skin. But in spite of its well known clinical and histologic appearances, there is but little information in the literature concerning the type which is associated with pigment. It is true that a few cases in which pigmentation was a marked, if not a predominating, feature have been presented before dermatologic societies in this country and in Cuba.
