Intraocular tumor diagnosed two years after perforating trauma

We describe the unusual diagnosis of a ciliary body medulloepithelioma by histopathology of a subretinal membrane obtained from vitreoretinal surgery of a 10-year-old boy. The patient had a history of perforating trauma OS 2 years earlier, and both fundus exam and B-scan ultrasound revealed only a retinal detachment with a subretinal membrane. No detectable mass was present. The membrane removed from underneath the peripheral retina revealed a blue cell tumor confirmed by histopathology and immunohistochemistry to be a primitive neuroectodermal tumor. Currently, the patient has been followed for 5 years with no signs of recurrence.
