Abstract
We present a unique case of an aggressive scapular osteoblastoma that produced β-hCG as a paraneoplastic manifestation in a 20-year-old woman. Serum β-hCG was found to be elevated during presurgical workup and consequently delayed surgical resection of the increasingly painful tumor because of suspected pregnancy. The paraneoplastic production of β-hCG was later proven by positive immunohistochemical stain of β-hCG in a curettage specimen and normalization of β-hCG levels after surgical resection of the aggressive osteoblastoma. Production of beta-human chorionic gonadotropin (β-hCG) has been reported in several carcinomas and sarcomas but, to our knowledge, it has not been reported in osteoblastoma in the English-language literature.
