Unusual case of intraocular medulloepithelioma in an adult male

Medulloepithelioma is a rare tumor of the eye, arising from the posterior segment. This embryonic tumor is mostly seen in children and is very rare in adult population. This case report presents the case of a 39-year-old Indian male, who had gradual vision loss over 4 years in his left eye with new onset of pain. He was referred to our center in view of secondary cataract and intraocular mass. Vision in right eye was 20/ 20 while left eye had no light perception at presentation. Ocular examination of the left eye revealed shallow anterior chamber, florid iris neovascularization, raised intraocular pressure and cataractous lens. B-scan ultrasonography showed a heterogenous mass filling the entire globe. MRI scan confirmed the finding, showing a mass hyper-intense to vitreous. No invasion of optic nerve or sclera was observed. Left eye enucleation with PMMA implant placement was performed and histopathology confirmed the diagnosis of benign teratoid medulloepithelioma. At the time of submission of this report, the patient was still under follow-up and had no detectable metastases at 15 months follow-up. This report highlights a very rare case of embryonic tumor in adult male, which could be managed successfully with a high index of suspicion and timely intervention.
