副腮腺肿瘤临床分析

目的　探讨副腮腺肿瘤的临床、影像、病理特点及治疗效果。方法　收集并分析我院经治的8例副腮腺肿瘤病例资料。结果　多形性腺瘤5例，基底细胞腺瘤、多 形性腺瘤恶变（高分化非特异性腺癌）、高分化鳞状细胞癌各1例。良性肿瘤病例的CT表现为肿块呈椭圆形、边界清楚、密度均匀；恶性肿瘤病例的CT表现为肿块形状不规则、境界不清、密度欠均匀。8例患者均行手术治疗，入路分别选择：1例面颊部直接切口，2例口内入路，5例标准腮腺肿瘤切除入路，鳞状细胞癌病例同时行选择性颈清扫术。2例恶性肿瘤患者术后辅以放疗。所有患者治疗后随访1～5年，无复发及转移。结论　副腮腺肿瘤CT表现具有一定的特征性，彻底切除是首选治疗，入路宜选用标准腮腺切除切口，恶性肿瘤术后辅以放疗，短期疗效较好。

Clinical analysis of accessory parotid gland tumors

OBJECTIVE To investigate the clinical, imaging and pathologic characteristics of accessory parotid gland tumors （APGTs）, and prognosis of the patients. METHODS Eight cases of APGTs were diagnosed and treated in Wuxi Second People＇s Hospital from Aug. 2008 to Dec. 2012, and the clinical data of them were analyzed retrospectively. RESULTS Five cases were pleomorphic adenoma, and the other 3 eases were basal cell adenoma, malignant pleomorphic adenoma （high differentiated non- specific adenocarcinoma）, and high differentiated squamous cell carcinoma respectively. CT scan showed midcheek mass with oval in shape, clear boundary and homogeneous density in 6 cases of benign tumors, and while irregular shape, not clear boundary and lack of uniform density in 2 malignant tumors. All patients were treated with operation, and radiotherapy for malignant cases was performed postoperatively. All patients had no recurrence or metastasis during following-up. CONCLUSION APGTs have certain characteristics on CT scan. Operation is the initial method to treat them, and the conventional parotid tumor resection approach is the optimal treatment. Malignant tumors may be supplemented with radiotherapy postoperatively. The prognosis is good after treatment, whether benign or malignant APGTs.
