Basal Cell Adenocarcinoma

Abstract

Basal cell adenocarcinoma is the malignant counterpart of basal cell adenoma. Basal cell adenocarcinoma affects primarily adults and presents at a mean age of approximately 65 years. Women and men are involved with similar frequency. The majority of cases involve the parotid gland, presenting as single or multiple masses. Basal cell adenocarcinoma is infiltrative, comprised of multiple cell types (ductal and basal), and may exhibit a variety of architectural patterns (solid, trabecular, tubular, and membranous) (Figs. 9.1, 9.2, 9.3, 9.4, 9.5, 9.6, 9.7, 9.8, 9.9, 9.10, 9.11, 9.12, 9.13, 9.14, 9.15, 9.16, 9.17, 9.18, 9.19, 9.20, 9.21, 9.22 and 9.23).
