Abstract

A 23-year-old man had a lesion in the right inferior iris which appeared to have enlarged since it was first seen when the patient was aged 5 years. The lesion was excised by a partial iridocyclectomy. Histopathologically the neoplasm was composed of both pigmented and non-pigmented cells. Pseudoacini, containing acid mucopolysaccharides, were present throughout the tumour matrix. Electron microscopically the non-pigmented cells were found to possess a convoluted plasmalemma, abundant rough endoplasmic reticulum, and numerous desmosomes and gap junctions. The pigmented cells contained large, round, mature melanosomes, occasional premelanosomes, and desmosomes, which resembled the posterior pigment epithelium of the iris. The intercellular matrix contained fine collagen fibrils resembling vitreous. We believe that this neoplasm represents a congenital adenoma of the ciliary body and iris.

摘要

一名23岁男性右眼下虹膜有一病变，自患者5岁首次发现以来似乎有所增大。该病变通过部分虹膜睫状体切除术切除。组织病理学检查显示，肿瘤由色素细胞和非色素细胞组成。肿瘤基质中可见含有酸性粘多糖的假腺泡。电子显微镜检查发现，非色素细胞具有卷曲的质膜、丰富的粗面内质网以及大量的桥粒和缝隙连接。色素细胞含有大的、圆形的、成熟的黑素小体，偶尔可见前黑素小体，还有桥粒，类似于虹膜后色素上皮。细胞间基质含有类似于玻璃体的细胶原纤维。我们认为该肿瘤为睫状体和虹膜的先天性腺瘤。
