Myoepithelial carcinomas (MCs) are difficult to distinguish from their benign counterpart due to diverse morphology. This neoplasm was introduced by Stromeyer . in 1975. They comprise of <2% of all salivary gland carcinomas involving most commonly major salivary glands and are characterized by differentiation of tumor cells into myoepithelial cells. The cells may present as epithelioid, plasmacytoid, spindle, clear, stellate and mixed type predominantly. Literature search revealed very few cases reported as clear cell variant of MC. Here, we report a case of clear cell MC involving buccal vestibule extending up to alveolus. The diagnosis was confirmed, and the patient was surgically treated.
肌上皮癌（MCs）因其形态多样，难以与良性对应物区分开来。这种肿瘤由斯特罗迈尔于1975年首次提出。它们占所有涎腺癌的比例不到2%，最常累及大涎腺，其特征是肿瘤细胞向肌上皮细胞分化。细胞主要表现为上皮样、浆细胞样、梭形、透明、星状及混合型。文献检索显示，报道为MC透明细胞变体的病例非常少。在此，我们报告一例累及颊前庭并延伸至牙槽的透明细胞MC病例。诊断得到证实，患者接受了手术治疗。
