Mesenchymal Chondrosarcoma Arising in Extraskeletal Soft Tissue -Report of a case-
A case of extraskeletal mesenchmal chondrosarcoma is presented in a 31 year old woman. The tumor occurred in the soft tissue overlying posteromedial aspect of the right tibial midshaft. The literature was reviewed and, to our knowledge, this is the first reported case in Korea. The tumor measured 9.0×5.0×4.0 cm, and was firm in consistency and yellow in color. Cut surface showed yellowish brown fibrotic surface with central calcification. The hisologic findings were characterized by islands of well differentiated cartilage and by undifferentiated mesenchmal tissue composed of sheets or lobules of small tumor cells arranged in a hemangiopericytomatous configuration, confirming the histopathological findings in the previously published reports.
