Retinal oligodendroglioma.

Abstract

To report a case of oligodendroglioma originating from the accessory glia of retina. Case report of a 72-year-old woman with a tumor in the temporal fundus of the right eye that was suspected to be choroidal melanoma. Enucleation was declined, but 5 years later, because of tumor growth, pain, and loss of light perception, the globe was enucleated. Histopathologic examination disclosed a neuroepithelial tumor with a structure of oligodendroglioma. Melanoma and metastatic tumor were excluded. Oligodendrogliomas are rare in the retina but may originate from retinal oligodendrocytes. This case suggests that the differential diagnosis of choroidal melanoma should include the possibility of oligodendroglioma.
