我们报道罕见的脉络膜黑色素细胞瘤1例,以视网膜母细胞瘤之诊断行眼球内容物剜除术。患儿14mo,以左眼外斜视约10mo主诉就诊。眼科检查及影像学检查显示视网膜脱离并钙化病灶。患儿诊断为视网膜母细胞瘤,患眼行眼球内容物剜除术。组织病理学检查显示肿瘤细胞体积大,多面体型,核小,胞浆含大量黑色素颗粒,提示脉络膜及睫状体黑素细胞瘤之诊断。以往有脉络膜及睫状体黑色素细胞瘤表现类似与恶性黑素瘤的报道,但是,黑色素细胞瘤表现为钙化病灶及视网膜脱离,被误诊为视网膜母细胞瘤,此病例罕见,以往未见报道。
We report a rare choroidal melanocytoma in 1 case, the diagnosis of retinoblastoma eyeball content excision. Children 14mo, left eye exotropia about 10mo complaints. Eye examinations and imaging studies showed retinal detachment and calcification of the lesion. Children diagnosed as retinoblastoma, suffering from ocular eyeball content excision. Histopathological examination showed that the tumor cells were bulky, polyhedral, nucleus, cytoplasm containing a large number of melanin particles, suggesting the diagnosis of choroid and ciliary body melanocytoma. In the past choroidal and ciliary body melanocytoma showed similar performance and malignant melanoma, however, melanocytoma showed calcified lesion and retinal detachment, was misdiagnosed as retinoblastoma, rare in this case, has not been previously reported.
