Abstract

Carcinoma ex pleomorphic adenoma (Ca ex PA) is a rare malignancy that represents a transformation of a primary pleomorphic adenoma (PA), or carcinoma arising from primary (de novo) or recurrent or pre-existing pleomorphic adenoma (PA). Pleomorphic adenoma is a benign mixed common neoplasm that arises from the major salivary gland. Here we are presenting a case report of a 60-year-old female patient with a history of swelling in her right parotid region for 1 year. After a thorough clinical and histological examination it is diagnosed as carcinoma ex pleomorphic adenoma (Ca ex PA). In our case report, we are more emphasizing the histological behavioral pattern of Carcinoma ex pleomorphic adenoma in preexisting pleomorphic adenoma (Ca ex PA) as distinctive histological features of this rare tumor play an essential role in the diagnosis of this tumor and thus, aid in the correct treatment plan and better prognosis.
