272例原发性泪腺上皮性肿瘤的病理分类

PRIMARY EPITHELIAL LACRIMAL GLAND TUMORS: THE PATHOLOGIC CLASSIFICATION OF 272 CASES

本文报道原发性泪腺上皮性肿瘤272例的组织病理分类,并与涎腺肿瘤的病理分类相比拟,本组大量泪腺肿瘤代表390例泪腺窝病变的70％,占一个医院中1530例眼眶肿瘤的18％。本组泪腺肿瘤中,良性混合瘤居首位(52％)次为腺样囊性癌(25％),再次为恶性混合瘤(9％)。少见的泪腺肿瘤中,作者首先识别出3例泪腺低度恶性多型性腺癌,2例梭形细胞形肌上皮瘤,1例癌肉瘤。有关低度恶性多型性腺癌及梭形细胞型肌上皮瘤的鉴别诊断进行了一些讨论。

This paper reports the pathologic classification of 272 cases with primary epithelial lacrimal gland tumors in comparison with that of the salivary glands. The extensive series of lacrimal gland tumors accounts for 70% of the 390 lacrimal fossa lesions and 18% of the 1 530 orbital tumors in one single hospital. Benign mixed tumors ranked the first (52%), adenocystic .carcinomas the second (25%) and malignant mixed tumors (9%) the third. Among the other less common tumors the authors identified, for the firs...
