子宫腺瘤样瘤的病理形态

Histopathological analysis of the adenomatoid tumors of the uterus

目的研究子宫腺瘤样瘤的病理形态和子宫腺瘤样瘤与子宫其他良性肿瘤的区别。方法对４５１３例子宫标本中的腺瘤样瘤和描述为富于淋巴管、脂肪的子宫肿瘤进行复查，必要时补体切片请病理学家确诊，共诊断子宫腺瘤样瘤１８倒，按Ｌｅｅ和Ｔｉｌｔｍａｎ的诊断分型分为丛状型、腺管型和脉管型。结果１８例子宫腺瘤样瘤占同期子宫标本的０．４％，５０％的肿瘤位于近宫角处，肿瘤直径１～５ｃｍ，切面可见微小孔隙，镜下大部分表现为脉管样形态。多数肿瘤距离浆膜≤３．９ｍｍ。１８例均伴有平滑肌增生，未见浆膜增生和化生，亦不伴有子宫内膜增殖性病变。结论子宫腺瘤样瘤不少见，主要类型是脉管型。

To characterize the features of the adenomatoid tumors of the uterus and to analyze the difference between the adenornatoid tumors and other benign tumors in the uterus.Methods All cases that described previously as adenomatoid tumors and other lesions rich in lymphoducts and lipocytes from 4513 specimens of uterus were reviewed. According to Lee's and Tiltman'scriteria,the diagnosis were made up and divided them into three types: plexiform , tubular and canalicular patterns. The features and difference between adenomatoid tumors and other lesions of the uterus were observed pathologically.Results 18 cases of adenomatoid tumors of uterus were diagnosed. The incidence was 0. 4%. Half of them were situated in the cornuas region, ranged from l-5cm in size. 17cases were canalicular type, except one case. The deepth of 90% of the tumors was within 3. 9mm below serosa .without serosa′sepitheliosis, metaplasia and endometrial hyperplasia.Conclusions Adenomatoid tumors are not very rare in uterus. The main pattern of them is canalicular type.
