仙骨に発生した巨大な間葉性軟骨肉しゅの一例

Mesenchymal chondrosarcoma is a rather unusual chondroid tumor that was first described in 1959 by Lichitenstein and Bernstein. A case of mesenchymal chondrosarcoma is presented in this paper. The patient was a twenty-year-old man and referred to our clinic with chief compliants of pain in the gluteal region and uro-rectal incontinence. Radiological and histological examinations with needle biopsy revealed a feature of chondrosarcoma occurring in the sarcrum, that occupied almost whole pelvic cavity. High amputation of sacrum and resection of the tumor was performed. Fourmon the after surgery, neither evidence of reccurrence nor of metastasis was seen radiologically and clinically.Japanese cases of this rare tumor were reviewed and 21 cases, including the present case, were accepted. Clinical characteristics were similar to those of a series reported by Salvador et al.
