To present a case of organized vitreous hemorrhage masquerading an optic disc melanocytoma.
Optic nerve head melanocytoma is a benign slightly pigmented lesion arising from the edge of the disc presenting with a filed defect. Pigmented nature of the lesion in question due to presence of haemosidrin laden macrophages led a diagnostic dilemma. Trans vitreal biopsy confirmed the diagnosis.
Althought classical in presentation organized blood clots can masquerade a number of lesions including a melanocytoma as in the present scenario.
报告一例伪装成视盘黑色素细胞瘤的机化性玻璃体出血病例。
视神经乳头黑色素细胞瘤是一种起源于视盘边缘的良性、轻度色素沉着的病变，表现为视野缺损。由于存在含铁血黄素的巨噬细胞，该病变的色素性质导致了诊断困境。经玻璃体活检确诊了诊断。
尽管在表现上具有典型性，但机化的血凝块可能伪装成多种病变，如本例中的黑色素细胞瘤。
