Synovial sarcoma of the hypopharynx in pregnancy.

Synovial sarcomas of the hypopharynx are a rare form of soft tissue sarcomas. In the head and neck, they are most commonly found on the pharyngeal wall in areas that do not have synovial cells. We review a case of a 23 year-old pregnant female who presented to our hospital with acute airway obstruction due to a large hypopharynx lesion.
