泪腺肿瘤在眶内肿瘤中的发病率目前在国内仅见胡椿枝等报告101例眶内肿瘤中有泪肿肿瘤23例(22.8％)。在我科住院患者中该腺瘤居眶瘤的第二位(血管瘤居首)。一般认为在泪腺肿瘤中以混合瘤为多,Duke—Elder统计约占90％。临床上泪腺混合瘤术后常易复发且被视为具有恶性倾向。近年来我们曾遇到数例复发并有恶变者。现将1973年～1984年收治的51例泪器肿瘤中约50例(其中一例为泪囊粘液癌)做一临床分析结果如下:
The incidence of lacrimal gland tumors in intraorbital tumors is currently only seen in China. Hu Zizhi et al. reported that 101 cases of intraorbital tumors had lacrimal tumors in 23 cases (22.8%). The adenoma was the second most common tumor in our department (hemangioma). It is generally believed that there are more mixed tumors in lacrimal gland tumors, accounting for about 90% of Duke-Elder statistics. Clinically lacrimal gland mixed tumors often recur after surgery and are considered to have a malignant tendency. In recent years we have encountered several cases of relapse and malignant transformation. The results of a clinical analysis of about 50 cases of lacrimal neoplasms treated from 1973 to 1984 (including one case of lacrimal sac mucocus carcinoma) are as follows:
