A 56-year-old man presented with a pigmented iris nodule which showed prominent vessels and enlargement within 6 weeks. The tumour caused recurrent hyphemata. Differential diagnosis included a pigmented iris hemangioma and a malignant melanoma. A sectoriridectomy was performed. Histology revealed a stromal cavity filled with fibrin and abundant erythrocytes. A diagnosis of an iris varix was established. However, it has to be pointed out that the distinction between a varix of the iris and an iris hemangioma may be difficult not only clinically but also histologically, and that iris melanomas may produce hemangioma-like patterns.
一名56岁男性患者出现一个色素性虹膜结节，该结节在6周内出现明显血管并增大。肿瘤导致反复前房积血。鉴别诊断包括色素性虹膜血管瘤和恶性黑色素瘤。进行了扇形虹膜切除术。组织学检查显示一个充满纤维蛋白和大量红细胞的基质腔。确诊为虹膜静脉曲张。然而，必须指出的是，虹膜静脉曲张与虹膜血管瘤之间的区分不仅在临床上可能困难，在组织学上也可能如此，而且虹膜黑色素瘤可能产生血管瘤样形态。
