ABSTRACT
Carcinoma ex-pleomorphic adenoma (CaxPA) is a carcinoma arising from a primary or recurrent benign pleomorphic adenoma (PA). It presents approximately 11.6% of all malignant neoplasms of salivary gland and mostly originates from major salivary glands. It is a common histologic subtype of primary parotid malignancy. Location in the minor salivary gland is uncommon and occurs in less than 7% of all cases. The majority of CaxPA develops from epithelial component of PA. Salivary gland tumors are known to have a benign clinical behavior with unrecognized metastatic potential. It often poses a diagnostic challenge to clinicians and pathologists. The entity is difficult to diagnose preoperatively. Pathologic assessment is the gold standard for making the diagnosis. We present a case of a 55-year-old female patient who had a right preauricular mass of 10 years duration, with sudden onset of pain of duration of 1 month.
