Abstract:
The Ewing's sarcoma comprises approximately less than 10 percent of malignant bone tumors and 5 percent of allbone tumors, occures in almost all bones of the body, and presents a widely divergent roentgenographicmanifestations. The tarsal bones are involved only 2 percent in the Ewing's sarcoma. Two cases experienced byauthors and ten cases published in literatures of Ewing's sarcoma of the tarsal bone were analizedretrospectively. The result were as follows; 1. Of tarsal bones, the calcaneus was 7 cases, the talus 4 cases,cuneiform 1 case. 2. Female was affected more commonly than male, the ratio being 4 to 1 in the tarsal bones. 3.About sixty percent of total case in the tarsal bones had evidence of diffuse sclerotic pattern. All the cases ofthe talus had evidence of diffuse sclerotic pattern. 4. The diseases to be considered in differential diagnosisare as follows: avascular necrosis, tuberculous osteomyelitis, osteosarcoma, and pyogenic osteomyelitis. 5. Thediffuse sclerosis radiographically showed a close relation with dead bone resulting from avascular necrosis due totumor infiltration histologically. Periosteal reactive new bone and osteoid deposition on the dead bone were alsocorrelated with diffuse sclerosis. 6. Because it is difficult to differentiate sclerotic lesions in the tarsalbones by radiographic methods alone, all such lesions should be subject to biopsy as early as possible.
