Primary Pulmonary Synovial Sarcoma in a 49-Year-Old Male

Abstract

Sarcoma is a malignant tumor arising from the mesenchymal tissues such as striated skeletal and smooth muscles, adipose tissue, bone, cartilage, and synovial tissue. The synovial subset of primary pulmonary sarcoma is very rare and is only described in a handful of cases. Our case describes the diagnostic approach and treatment regimen for a 49-year-old male with no significant past medical history. The diagnosis of a primary pulmonary synovial sarcoma was made through the use of endobronchial ultrasound (EBUS), transbronchial needle aspiration (TBNA), histologic analysis, and immunostaining. The treatment utilized a multimodal approach including resection, chemotherapy, and radiotherapy.
