ABSTRACT

Giant cell tumor (GCT) of bone is a rare neoplasm that accounts for approximately 5% of all primary bone tumors in adults. Sacrum is an unusual site for giant cell tumor and it is an intriguing and unpredictable entity with a high predilection for recurrences. We hereby report 2 cases of Giant cell tumor of sacrum occurring in a 42- year- old male and a 17- year- old female. The tumor recurred twice in the 42- year- old male and was treated with surgery radiotherapy and embolization, whereas the tumor did not recur in the 17- year- old female who was operated for the same.
