Abstract

Carcinoma ex pleomorphic adenoma is the malignant counterpart of pleomorphic adenoma. Carcinoma ex pleomorphic adenoma affects primarily adults and presents at a mean age of approximately 60 years. Women are involved more than men. The majority of cases involve the parotid gland, presenting as single or multiple masses. Carcinoma ex pleomorphic adenoma may be well-circumscribed (noninvasive) or infiltrative (invasive), comprised of multiple cell types (ductal, myoepithelial, and chondromyxoid stromal), and exhibit a variety of architectural patterns (solid, cystic, and cartilaginous) (Figs. 23.1, 23.2, 23.3, 23.4, 23.5, 23.6, 23.7, 23.8, 23.9, 23.10, 23.11, 23.12, 23.13, 23.14, 23.15, 23.16, 23.17, 23.18, 23.19, 23.20, 23.21, 23.22, 23.23, 23.24, 23.25, 23.26, 23.27, 23.28, 23.29, 23.30, 23.31, 23.32, 23.33, 23.34, 23.35, 23.36, 23.37, 23.38, 23.39 and 23.40).
