Abstract
A 70-year-old man, with renal failure, applied with the complaint of shortness of breath. Thoracic computed tomography revealed dense intraluminal fields at distal trachea. The bronchoscopy revealed a solid mass, located on the lateral wall of the trachea (Fig. 1). During bronchoscopy, an endobronchial mass excision with laser was performed. The immunohistochemical examination revealed that the tumor cells reacted positively to vimentin and friend leukemia integration (FLI)-1, and negatively to desmin, CD31, S-100, and pancytokeratin (Figs. 2 and 3). The findings were consistent with ES. Due to the suspicions concerning the surgical margin, radiotherapy (RT) was recommended. Postoperatively, 50.4-Gy RT was applied. Metastatic lesions in the scalp and humerus were revealed 3 months after the RT. Chemotherapy could not be performed because of the renal insufficiency. The patient died 8 months after surgery due to renal failure.
