Osteoblastoma is a rare primary bone tumor that is curable by complete
excision. There are few data about the effectiveness of chemotherapy
or radiotherapy in the treatment of recurrent osteoblastoma. We report
a 13-year-old girl with recurrent osteoblastoma who, after in complet
e surgical excision, responded to treatment with radiotherapy and late
r with chemotherapy. Surgery remains the treatment of choice for osteo
blastoma. Radiotherapy and chemotherapy either alone or together may b
e useful in selected patients with recurrent, aggressive tumor or in p
atients with surgically unresectable disease. (C) 1997 Wiley-Liss, Inc
