A mucoepidermoid tumour of the tongue.

A case of mucoepidermoid tumour arising in minor salivary glands of the tongue and assessed histologically to be of high-grade malignancy is described. The diagnostic difficulties involved in distinguishing the neoplasm from a squamous cell carcinoma are considered. From published figures it would appear that salivary gland neoplasms in the tongue are much more likely to be malignant than benign.
