Synovial Sarcoma of the Hypopharynx in a Filipino Female: A Case Report

Synovial sarcoma of the hypopharynx is an uncommon malignancy, with less than 100 cases reported in available journals. We report a case of a 22-year-old female presenting with dysphagia and enlarging hypopharyngeal mass, clinically diagnosed as hypopharyngeal malignancy, right, at least stage III. Histopathologic examination including immunohistochemistry study with TLE1 and SS18 Fluorescence In Situ Hybridization (FISH) confirm the diagnosis of synovial sarcoma. This is the first reported case of synovial sarcoma of the hypopharynx in the Philippines confirmed by SS18 FISH. Due to the size of the mass, chemoradiotherapy followed by surgery is the current plan of management for this patient.
