This 57YO male presented with a retinocytoma without any history of retinoblastoma (RB) or treatment for RB.
Clinically, retinocytomas can resemble astrocytic hamartomas. However, retinocytomas often have underlying RPE changes and chorioretinal scarring, which are not present in astrocytic hamartomas.
Learning Points:
Retinocytomas are fleshy, opalescent, benign tumors that are thought to spontaneously regress in Rb. They appear identical to previously radiated Rb tumors.
Similar to typical RB, these patients’ offspring are at a 50% risk for developing Rb and thus require genetic counseling.
