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.
肌上皮瘤是一种罕见的良性肿瘤，主要累及腮腺，较少累及小唾液腺。在本文中，我们报告了3例具有不同组织形态学模式的病例。其中2例来自口腔，1例来自鼻窦道，后者是非常罕见的发病部位。我们讨论了肌上皮瘤不同的组织形态学模式，这些模式有时给病理学家带来真正的诊断难题。除了其形态学，还详细讨论了免疫组化特征和临床行为，并对相关文献进行了综述。
