探讨涎腺嗜酸细胞腺癌的临床特征、诊断与治疗。对21例涎腺嗜酸细胞腺瘤的临床资料进行统计分析,其中嗜酸细胞腺瘤12例,占57.14％;恶性嗜酸细胞腺瘤9例,占42.86％。发病年龄以青壮年多见。良性病例生长缓慢,病程长,极易误诊为多形性腺瘤;恶性病例病程短,原发瘤呈迅速浸润性生长。由于该瘤是多中心性生长,术后极易复发;恶性者颈淋巴和脑、肺转移率高。确切诊断须依赖组织病理学检查,首次彻底手术切除是治疗成功的关键,恶性瘤体>2cm者应作选择性淋巴结清扫术,术后酌情实施局部放疗和全身化疗。
To investigate the clinical features, diagnosis and treatment of salivary gland eosinophilic adenocarcinoma. The clinical data of 21 cases of salivary acidophilic adenoma were analyzed statistically, including 12 cases of eosinophilic adenoma, accounting for 57.14%; 9 cases of malignant eosinophilic adenoma, accounting for 42.86%. Age of onset to more common in young adults. Benign cases of slow growth, long course, easily misdiagnosed as pleomorphic adenoma; malignant cases of short duration, the primary tumor showed rapid infiltration of growth. Because the tumor is multicentric growth, postoperative easily relapse; malignant cervical lymphatic and brain, lung metastasis rate. The exact diagnosis depends on histopathological examination, the first complete surgical resection is the key to the success of treatment, malignant tumor> 2cm should be made for selective lymph node dissection, after surgery, as appropriate, the implementation of local radiotherapy and systemic chemotherapy.
