title: Rhabdomyosarcoma of the ciliary body.
abstract: Rhabdomyosarcoma is the most common malignant orbital tumor of childhood. It has twice been reported to arise within the globe from the iris. In addition, teratoid medulloepithelioma, a tumor arising from the ciliary epithelium, can contain a rhabdomyoblastic component, often in combination with other heteroplastic elements. The authors report what may be the first recorded case of an embryonal rhabdomyosarcoma of the ciliary body, possibly representing a one-sided differentiation of a malignant teratoid medulloepithelioma.
