Abstract
Myoepithelioma is a rare neoplasm of the salivary glands, generally occurring in the parotid gland and less often in the minor accessory salivary gland of the oral cavity. The histological appearance includes solid, myxoid and reticular growth patterns. Vimentin and S-100 protein are very sensitive but non-specific immunohistochemical markers of neoplastic myoepithelium. Conservative surgery is the treatment of choice. A case of myoepithelioma of the minor salivary gland of the cheek with low grade malignancy is described, focusing on clinical behaviour, histopathological and immunohistochemical features and differential diagnosis.
摘要
肌上皮瘤是一种罕见的唾液腺肿瘤，通常发生于腮腺，较少见于口腔小唾液腺。其组织学表现包括实性、黏液样和网状生长模式。波形蛋白和S-100蛋白是肿瘤性肌上皮非常敏感但非特异性的免疫组化标志物。保守性手术是首选治疗方法。本文描述了一例低度恶性的颊部小唾液腺肌上皮瘤病例，重点介绍其临床行为、组织病理学和免疫组化特征以及鉴别诊断。
