Pleomorphic adenoma is the most common benign tumor of the salivary glands. Histologically, it is characterized by the presence of both epithelial and mesenchymal elements and may contain various metaplastic changes. This paper reports a case of pleomorphic adenoma with extensive mucinous metaplasia, which is histologically very similar to mucoepidermoid carcinoma. Pleomorphic adenoma with extensive mucinous and squamous differentiation may be misdiagnosed as mucoepidermoid carcinoma. Immunohistochemistry was ineffective in differential diagnosis, and the diagnosis was confirmed by the absence of mastermind like transcriptional coactivator 2 translocation.
