title: Malignant fibrous histiocytoma masquerading as germ cell tumor by producing beta-human chorionic gonadotropin and neuron-specific enolase.
abstract: Neuron-specific enolase and beta-human chorionic gonadotropin are serum markers frequently found associated with germ cell tumors. To our knowledge, we report the first case of a malignant fibrous histiocytoma producing both markers and discuss the significance of this unusual condition in the differential diagnosis of retroperitoneal tumors.
