Primary synovial sarcoma of the lung: Case report and review of the literature

Abstract

Primary synovial sarcoma of the lung is a rare pathology, representing around 0.5% of malignant lung neoplasms. Clinically, it is manifested by pleuritic chest pain, cough, hemoptysis, dyspnea, and weight loss. Diagnosis requires a good clinical history, imaging, and clinical and immunohistochemical studies. Its treatment is not fully established. However, complete surgical resection associated with chemotherapy has shown improvements in survival. This report presents the case of a 26-year-old male patient with dyspnea, chest pain, cough, and hemoptysis. Subsequently, a mass in the left hemithorax was evidenced using radiological studies, and surgical resection was performed. The anatomopathological and immunohistochemical findings suggest synovial sarcoma, for which a co-adjuvant chemotherapeutic scheme was started; the patient had an operative site infection during hospitalization and required intravenous antibiotic therapy, with subsequent favorable clinical evolution.
