Mucoepidermoid carcinoma is the most common malignant tumor of salivary gland. Majority of the salivary gland tumors arise in parotid gland with maximum being of benign nature. Although Mucoepidermoid carcinoma accounts for less than 10% of all tumors of the salivary gland, it constitutes approximately 30% of all malignant tumors of the salivary gland. It is characterized by a mixed pattern of the two main cell types: epidermoid and mucus-producing cells. Metastasis from salivary gland malignancy is infrequent and predominantly found in bone, lung, liver and lymph nodes. We are presenting a rare case of metastasis of mucoepidermoid carcinoma of parotid gland to the contralateral mandible.
黏液表皮样癌是唾液腺最常见的恶性肿瘤。大多数唾液腺肿瘤发生于腮腺，其中大部分为良性。尽管黏液表皮样癌在所有唾液腺肿瘤中占比不到10%，但它约占唾液腺所有恶性肿瘤的30%。其特征是两种主要细胞类型的混合模式：表皮样细胞和黏液产生细胞。唾液腺恶性肿瘤的转移并不常见，主要发生在骨、肺、肝和淋巴结。我们报告一例罕见的腮腺黏液表皮样癌转移至对侧下颌骨的病例。
