Chapter 10. Basal Cell Carcinoma

Definition

A malignant neoplasm made up of abnormal germinative cells analogous to those that compose the folliculosebaceous-apocrine germ in an embryo and that usually manifests clinically as a papule or nodule which may become ulcerated. On the basis of clinico-pathologic correlation, five distinctive types of basal cell carcinoma have been identified, namely, nodular, superficial, morpheiform, fibroepithelial, and infundibulocystic.
