ABSTRACT

Myoepithelioma is a rare benign neoplasm of salivary glands. Accounts for less than 1% of all salivary
gland neoplasms. It is more common in parotid glands foIIowed by small salivary glands.
Myoepithelioma once was considered as extreme variant of pleomorphic adenoma. But now-a-days
many authors consider the myoepithelioma as distinct pathological entity as it is composed
entirely of myoepithelial cells and behaves more aggressive than pleomorphic adenoma(PA). Here we are presenting a case of myoepithelioma-plasmacytoid variant of minor salivary gland of soft palate of a male patient aged about 60 years and discussing about histopathological differential diagnosis of myoepithelioma.
