Most reported cases are osteogenic sarcomas with soft tissue sarcomas encountered less often. We report a rare case of fibrosarcoma of the larynx, following radiation therapy for glottic carcinoma.

The tumor presented as an edematous swelling of the right vocal fold, appearing as a common Reinke edema.

On neurologic examination, the lesion was localized to spinal cord segments T3-L3. Magnetic resonance imaging of the spine showed an expansile mass occupying most of the ventral aspect of the spinous process of T6.
