Malignant rhabdoid tumor of the orbit in an infant.

We present the case of an infant with rapidly progressing orbital tumor that had initial radiological and clinical features of both rhabdomyosarcoma and capillary hemangioma. The patient was eventually diagnosed with malignant rhabdoid tumor of the orbit. We discuss the salient histological and radiological features of our case and review the literature on orbital malignant rhabdoid tumors.
