Abstract

Carcinoma ex pleomorphic adenoma (CEPA) is the malignant salivary gland tumor originating from primary (de novo) or recurrent pleomorphic adenoma. Although parotid gland is the most common site, it can also be seen in submandibular gland or minor salivary glands. It can be seen rarely in head and neck region, such as oral cavity, trachea, nasal cavity and lacrimal gland. Although pleomorphic adenoma cases originating from ectopic salivary gland tissue in the neck region are present in the English literature, there is no published pleomorphic adenoma ex carcinoma case. In this case report we presented a CEPA as a 7.5 cm long neck mass in a 72-year-old woman originating from the submandibular region apart from submandibular gland. Difficulties in diagnosis and way to appropriate treatment are discussed with current literature.
