Abstract

|
|
This is a case, in a 27 year-old female, of secondary chondrosarcoma originating from a solitary exostosis of the central portion of the left iliac bone.
Chief complaints were mild pain and a new hard growing mass which was just proximal to the left hip joint.
Roentgenological study revealed a solitary exostosis with a pedicle which grew out from the cen￢tral portion of the left ilium.
Surgical en bloc excision in rectangular shape was performed, including the left iliac crest, under the clinical suspicion of chondrosarcoma since it had begun to grow with new activity after her growth cessation.
Pathological diagnosis revealed an exostosis and there was no evidence of malignancy.
With recurrence of the tumor, left hemipelvectomy was advised, under the clinical diagnosis of secondary chondrosarcoma, but the patient refused. Two other surgical excisions were performed and pathological diagnosis revealed secondary chondrosarcoma.
A total of 6000 rad of radiation therapy was done.
A pulmonary metastasis was noticed 4 months after the 3rd operation.
Clinical findings were very important in the diagnosis of malignant change of the tumor.
