(a) Conventional radiograph reveals an osteolytic lesion in metadiaphysis of the left distal tibia with cortical destruction. (b) T1-Weightened Magnetic Resonance Image shows a well-defined low density intramedullary location with cortical breakthrough. (c) Interlacing
bundles of spindle cells with enlarged shaped atypical nuclei and eosinophilic cytoplasm (H&E, x40). (d) Tumor cells are immunostained by the antibody against Actin HHF-35.

Plain radiographs revealed a 5 cm osteolytic lesion involving the left distal tibia metadiaphysis with cortical destruction and no periosteal reaction (Figure 1).
(a) Abdominal computed tomography showing an hypodense lesion in the liver. (b) Tumor composed of fibrous stroma with myxohyaline areas
containing epithelioid cells with intracellular vacuoles (H&E, x20). (c) Tumor cells are immunostained with antibody to CD34.
