Key result
Transoral CO2 laser microsurgery successfully achieved en bloc removal with clear margins of a rare laryngeal synovial sarcoma in a 41-year-old male, leaving him disease-free and symptom-free.
Case Report (n=1)
Transoral CO2 laser microsurgery can be successfully used for en bloc resection of rare laryngeal synovial sarcomas presenting with airway obstruction.
May support laser microsurgery for rare laryngeal synovial sarcoma; hypothesis-generating and should not yet change practice.
An overwhelming majority of primary tumors of the hypopharynx are squamous cell carcinomas, accounting for approximately 95%. Synovial sarcoma (SS) is exceedingly rare at this anatomical site. A 41-year-old, otherwise healthy male presented with a 2-year history of dyspnea and dysphonia. Flexible laryngoscopy revealed a very large, well-circumscribed, pedunculated mass with near-total airway obstruction. On computed tomography imaging, a 4.7 cm × 2.6 cm supraglottic mass was demonstrated. Transoral CO2 laser microsurgery was carried out for en bloc removal. Final margins were clear and the patient is currently disease-free and symptom-free. Since the first case of head and neck SS was described in 1954, there have been fewer than 200 cases reported in the world literature. To the best of our knowledge, this is the first known case of a laryngeal SS that presented with airway obstruction which was managed with a negative-margin transoral CO2 laser microsurgery resection.

Shi et al. (2016) conducted a case report in Synovial sarcoma of the hypopharynx (n=1). Transoral CO2 laser microsurgery was evaluated on En bloc removal and disease-free status. Transoral CO2 laser microsurgery successfully achieved en bloc removal with clear margins of a rare laryngeal synovial sarcoma in a 41-year-old male, leaving him disease-free and symptom-free.
