title: Malignant giant cell tumor of the soft tissue: angiographic manifestations.
abstract: Two cases of malignant giant cell tumor originating within the soft tissues of the thigh are reported. In both instances, angiography demonstrated hypervascular masses with arterial and venous abnormalities indicative of an aggressive malignancy. The histopathologic appearance of the lesions was similar to that of osseous giant cell tumors. The clinical and radiographic features of this rare entity are briefly reviewed.
