腺瘤样瘤为男女生殖系统中较常见的良性肿瘤,对它的组织来源一直是争议的问题,曾有人认为它来自脉管内皮,但多数认为是间皮及Mullerman管源性。 角蛋白keratin为胞浆中中间丝蛋白之一,它为上皮细胞及其肿瘤特异的标记物,不同分子量的单克隆抗体可以染不同类型的上皮。一般认为间皮细胞 Adenomatous tumor is the most common benign tumor in male and female reproductive system. The source of its tissue has been a controversial issue. Some people think it is from the vascular endothelium, but most of them are considered to be mesothelial and Mullerman-derived.

Monoclonal antibodies of different molecular weights can dye different types of epithelium. Generally believed that mesothelial cells
