Mucoepidermoid carcinoma expleomorphic adenoma of the submandibular gland.
We described a rare case of carcinoma expleomorphic adenoma in which mucoepidermoid carcinoma arise from a previous incompletely excised pleomorphic adenoma of the submandibular gland. The tumor was surgically resected along with a modified radical neck dissection and postoperative radiotherapy. The patient remained disease free 3 years after the last operation. The pathology showed concurrent presence of Warthin's tumor in the specimen. The concurrent presence of mucoepidermoid carcinoma, pleomorphic adenoma, and synchronous Warthin's tumor make this case unique, and such a combination associated with the submandibular gland has not been documented in the literature before.
