Abstract：
Vascular conjunctival tumors are uncommon, usually benign lesions. Here, we report a 65-year-old male who presented with a nasal interpalpebral bulbar firm, oval, and dark-brown and non-mobile conjunctival mass. The systemic and ocular examinations including fundoscopy and gonioscopy were within normal limits. With a diagnosis of conjunctival malignant melanoma (CMM), the patient underwent excisional biopsy, partial sclerectomy, and cryotherapy. Microscopic examination revealed dilated vascular channels filled by red blood cells, separated by fibrous interstitium and no sign of malignancy. Therefore, a diagnosis of conjunctival cavernous hemangioma was made. Our case demonstrates that the conjunctival cavernous hemangioma can mimic malignant conjunctival lesions as well as extrascleral extension of uveal melanoma or uveal prolapse due to scleral necrosis.
摘要：
血管结膜肿瘤并不常见，通常是良性病变。这里,我们报告了一名65岁的男性，他出现了鼻睑间延髓，椭圆形,和深棕色和不可移动的结膜肿块。全身和眼部检查，包括眼底镜检查和房角镜检查均在正常范围内。诊断为结膜恶性黑色素瘤（CMM），患者接受了切除活检,巩膜部分切除术,还有冷冻疗法.显微镜检查显示红细胞填充的扩张的血管通道，被纤维间质隔开，没有恶性肿瘤的迹象。因此,诊断为结膜海绵状血管瘤。我们的病例表明，结膜海绵状血管瘤可以模仿恶性结膜病变以及由于巩膜坏死引起的葡萄膜黑色素瘤或葡萄膜脱垂的巩膜外延伸。
