Retinal oligodendroglioma

PURPOSE: To report a case of oligodendroglioma originating from the accesso ry glia of retina. METHOD: Case report of a 72-year-old woman with a tumor in the temporal fun dus of the right eye that was suspected to be choroidal melanoma. Enucleati on was declined, but 5 years later, because of tumor growth, pain, and loss of light perception, the globe was enucleated. RESULTS: Histopathologic examination disclosed a neuroepithelial tumor with a structure of oligodendroglioma. Melanoma and metastatic tumor were exclu ded. CONCLUSIONS: Oligodendrogliomas are rare in the retina but may originate fr om retinal oligodendrocytes. This case suggests that the differential diagn osis of choroidal melanoma should include the possibility of oligodendrogli oma. (Am J Ophthalmol 1999;128:389-391. (C) 1999 by Elsevier Science Inc.
