Primary thoracic giant cell tumor of bone sensitive to steroids.

Abstract

Spinal giant cell tumor of bone (GCTB) is a rare benign, but locally aggressive, entity. We report the case of a 40-year-old man diagnosed with GCTB of the thoracic spine. The only symptom upon presentation was progressive back pain with pain radiating to the chest. Magnetic resonance imaging showed that the soft tissue mass extended posteriorly into the spinal canal, causing severe spinal cord compression. We initially treated this case with Decadron (Fresenius kabi, Bad Homburg vor der Hohe, Germany) for 1 week. This led to a reduction of tumor size and decompression of the spinal cord. To the best of our knowledge, there have been no prior reports of primary GCTB sensitive to steroid therapy within the existing literature.
