A 49-year-old man developed a tumour mass in his right parotid salivary gland nine years after a histologically proven benign mixed tumour of the same salivary gland had been surgically removed. Radical resection of the right parotid salivary gland and associated lymph nodes and soft tissues of the neck was performed. The parotid tumour was composed of oncocytic cells which infiltrated the surviving salivary gland tissue. Most of the excised lymph nodes contained metastatic deposits of oncocytic cells identical to the tumour seen in the parotid. There are no previous reports of the occurrence of both pleomorphic adenoma and malignant oncocytoma in the same salivary gland.
一名49岁男性在其右侧腮腺涎腺的组织学确诊为良性混合瘤经手术切除9年后，右侧腮腺涎腺出现肿瘤肿块。对右侧腮腺涎腺以及相关颈部淋巴结和软组织进行了根治性切除。腮腺肿瘤由嗜酸性细胞组成，这些细胞浸润了残留的涎腺组织。大部分切除的淋巴结含有与腮腺肿瘤中所见相同的嗜酸性细胞转移灶。此前尚无同一涎腺中同时发生多形性腺瘤和恶性嗜酸性细胞瘤的报道。
