儿少期涎腺上皮性肿瘤的诊治特点

The diagnosis and treatment of the epithclial sali-vary gland tumors in children and adolescents

作者对６６例发生于１６岁以下的儿童及少年的涎腺上皮性肿瘤进行了临床分析。此６６例占同期涎腺上皮性肿瘤的３．６％。其中２５例为良性肿瘤，占３７．９％，以多形性腺瘤最多见；４１例为恶性肿瘤，占６２．１％，以粘液表皮样癌居首位。１０岁以上组５０例，占全部病例的３／４以上。５岁以下组仅６例，其中恶性肿瘤５例，表明患者年龄越小，患恶性肿瘤的可能性越大，且肿瘤分化程度低，恶性度高。２例腮腺癌患者曾因同侧腮腺区血管瘤而接受过放射治疗。放疗后８年，１例为粘液表皮样癌，１例为腺样囊性癌，表明恶性肿瘤的发生与放射治疗有关。作者对儿少期涎腺上皮性肿瘤的诊断、鉴别诊断及治疗进行了讨论，强调了首次手术彻底根治的重要性。

AbstractSixty-six cases with epithelial salivary gland tumorsin children and adolescents, who were less than 16 yearsold, were analized. Those cases accounted for 3. 6% ofall epithelial salivary gland tumors in our school. Twen-ty-five cases(37. 9%)were benign tumors, amongwhich pleomorphic adenoma was the most common.Forty-one cases(62. 1%)were malignant tumors, inwhich mucoepidermoid carcinoma was the most commonone.Three quarters of cases were in the group over 10years old.Six cases were in the group less than 5 yearsold. Among them 5 cases were malignant tumors. Theyounger the children is, the more possible the malignanttumor is. Two cases with malignant tumors had the his-tory of receiving radiotherapy because of the heman-giomas at the same locations. It indicates that the occur-rence of the malignant tumors was related to radiothera-py before. The diagnosis, differential diagnosis andtreament of the tumors were discussed. The initial radi-cal resection of the malignant tumors was emphasized.
