Endolaryngeal synovial sarcoma: Case report with immunohistochemical studies

Endolaryngeal synovial sarcoma has only been reported in the literature three times. We add to this a fourth report of a 28‐year‐old woman. This case distinguishes itself by being a monophasic variant and by being the first to be substantiated with extensive immunohistochemical analysis. Treatment consisted of shelling‐out followed by radiotherapy, which is a variant from standard therapy. The patient is tumor‐free 3 years after therapy.
