Retinoblastoma is the most common intraocular neoplasm in children. Glial tumor of the retina and optic nerve head are considered to be congenital and are therefore classified as hamartomas. Concurrent occurrence of these tumors in one eye is uncommon and by reviewing the studies, a few cases have been reported. We report a 9 years old boy with eye enucleation and concurrent occurrence of retinoblastoma and astrocytoma in one eye as two separate and different masses. Although retinoblastoma and astrocytoma are two distinct tumors and their concurrent occurrence in one eye is rare, concurrent occurrence of these tumors may suggest differentiation of these two tumors from a neuroectodermal primary cell.
视网膜母细胞瘤是儿童最常见的眼内肿瘤。视网膜和视神经乳头的胶质肿瘤被认为是先天性的，因此被归类为错构瘤。这些肿瘤在一只眼睛中同时出现并不常见，通过查阅研究资料，仅有少数病例被报道。我们报告了一名9岁男孩，其眼球被摘除，视网膜母细胞瘤和星形细胞瘤在一只眼睛中作为两个独立且不同的肿块同时出现。尽管视网膜母细胞瘤和星形细胞瘤是两种不同的肿瘤，它们在一只眼睛中同时出现很罕见，但这些肿瘤的同时出现可能提示这两种肿瘤都起源于神经外胚层原始细胞。
