Optic disc melanocytoma with vitreous seeding, epiretinal membrane, systemic hypertension, and acral vitiligo: a case study

Melanocytoma is a rate benign pigmented tumor arising from melanocytes. The lesion could be found intraocularly at any age, but the average age is 50 years with a slight female predilection (63% of the cases). Although most tumors are asymptomatic, some patients may develop visual symptoms caused by neural, vascular compression, or tumor necrosis. A 69-year-old female patient presented for checking of her glasses. A routine fundus examination revealed a pigmented dark brown lesion partially obscuring the optic nerve head, along with the presence of vitreous floaters. A provisional diagnosis of optic disc melanocytoma (ODMC) was subsequently confirmed through B-scan ultrasonography and optical coherence tomography imaging. The patient also exhibited systemic associations, including systemic hypertension and acral vitiligo. This report highlights the uncommon association of ODMC with vitreous seeding, epiretinal membrane formation, systemic hypertension, and the first documented case of ODMC associated with acral vitiligo.
