Myoepithelioma of minor salivary glands – A diagnostic challenge: Report of three cases with varied histomorphology

Myoepitheliomas are rare, benign neoplasms affecting predominantly parotid gland and to a lesser extent minor salivary glands. In this article we have reported three cases with different histomorphological patterns. Two cases are from oral cavity and one from sinonasal tract, a very rare location. We have discussed different histomorphological patterns of myoepitheliomas, which at times possesses a real diagnostic dilemma to a pathologist. Along with its morphology, immunohistochemical profile and clinical behavior are discussed in detail with relevant review of literature.
