Ipsilateral salivary gland tumors of different histologic types are rare and make up less than 0.3% of all salivary gland neoplasms. Only nine cases of synchronous benign and malignant ipsilateral parotid gland tumors have been described in the literature.
Two additional cases of synchronous benign and malignant neoplasms in the parotid gland are reported and discussed with a review of literature.
Our first case describes a pleomorphic adenoma and a salivary duct carcinoma, an entity not previously reported in the literature. The second case documents the most common benign and malignant ipsilateral parotid gland neoplasm reported in this case series, a Warthin's tumor and a mucoepidermoid carcinoma.
Synchronous salivary gland tumors exhibiting both benign and malignant components are uncommonly observed, with only nine cases published to date. We describe two additional cases of a synchronous benign and malignant ipsilateral parotid gland tumor.
不同组织学类型的同侧涎腺肿瘤较为罕见，占所有涎腺肿瘤的比例不到0.3%。文献中仅描述了9例同侧腮腺同步发生的良性和恶性肿瘤。
报告另外2例腮腺同步发生的良性和恶性肿瘤病例，并结合文献回顾进行讨论。
我们的第一例病例为多形性腺瘤和涎腺导管癌，这是文献中此前未报道过的一种组合。第二例病例记录了本病例系列中报道的最常见的同侧腮腺良性和恶性肿瘤，即沃辛瘤和黏液表皮样癌。
同时具有良性和恶性成分的同步涎腺肿瘤很少见，迄今为止仅有9例发表。我们描述了另外2例同侧腮腺同步发生的良性和恶性肿瘤病例。
