Polymorphous adenocarcinoma (PAC) is a rare salivary gland tumor, usually seen in minor salivary glands. It primarily affects adult females. Herein, we report an unusual case of polymorphous adenocarcinoma in a 72 year old male who presented with the non specific symptoms of swelling and mild pain below right lobe of ear similar to the pleomorphic adenoma. On Fine Needle Aspiration Cytology (FNAC), an impression of pleomorphic adenoma was given. Contrast enhanced computed tomography (CECT) of the neck was done, showed a relatively defined heterogenous enhancing soft tissue attenuated mass lesions suggesting likely neoplastic in nature, arising from parotid gland. Histopathological examination and immunohistochemistry (IHC) confirmed the diagnosis of polymorphous adenocarcinoma. Patient was conservatively managed and wide local excision was performed. Polymorphous adenocarcinoma should be included in the differential diagnosis of pleomorphic adenoma to avoid recurrence of the lesion.
