Carcinoma ex pleomorphic adenoma (CXPA) is a rare malignant salivary gland tumor, mostly involving the parotid and submandibular glands. Minor salivary gland involvement is even rarer, palate being the most common site. Other reported sites are upper lip, sinonasal tract, and buccal mucosa. Here, we report a case of CXPA in an unusual location, the floor of the mouth.
