Primary atypical rhabdoid orbital tumor: An entity with aggressive behavior

Abstract

Malignant rhabdoid tumors are rare, poorly differentiated tumors which usually affect children under the age of three. These tumors have a predilection for the kidney, central nervous system and soft tissue. The definition classically relies on a characteristic morphology and the inactivation of the hSNF5/INI1 tumor suppressor gene. The diagnosis is based on radiological explorations, as well as anatomopathological and immuno-histochemical studies.Whatever the location of the tumor, the therapeutic protocol is only decided after multidisciplinary consultation meeting, while resorting to a triad of chemotherapy, surgery and radiotherapy. The prognosis remains poor and the survival rate is below 30%. We report a rare case of retro-orbital malignant rhabdoid tumor of a new born girl.
