Polymorphous Adenocarcinoma

Abstract

Polymorphous adenocarcinoma affects children and adults and presents at a mean age of approximately 60 years. Women are involved more than men. The majority of cases involve minor salivary glands, presenting as single or multiple masses. Most cases of polymorphous adenocarcinoma behave as low- to intermediate-grade malignancies. Polymorphous adenocarcinoma may be well-circumscribed or infiltrative, comprised almost exclusively of one cell type (ductal), and exhibit a variety of architectural patterns (solid, trabecular, cribriform, microcystic, and papillary-cystic) (Figs. 24.1, 24.2, 24.3, 24.4, 24.5, 24.6, 24.7, 24.8, 24.9, 24.10, 24.11, 24.12, 24.13, 24.14, 24.15, 24.16, 24.17, 24.18, 24.19, 24.20, 24.21, 24.22, 24.22, 24.23, 24.24, 24.25, 24.26, 24.27 and 24.28).
