title: Plantar basal cell carcinoma: a case report.
abstract: Basal cell carcinoma, the most common type of skin cancer, is usually found in Caucasians between 50 and 70 years of age who are frequently exposed to sunlight or x-irradiation. They are rarely found in blacks and are seldom seen on the palmar or plantar surfaces. Dr. Galinski reports on a black male with a basal cell carcinoma on the planter surface of his right foot. Squamous cell carcinoma, keratoacanthoma, seborrheic keratosis, and sebaceous hyperplasia resemble basal cell carcinoma and must be considered in a differential diagnosis. Unlike most tumors, basal cell carcinomas spread by direct extension.
