Primary Ewing sarcoma (ES) of the lung is anecdotally rare, with few cases reported in literature. This report describes a 46 year‐old man who presented with cough and chest pain. CT Thorax revealed a lesion in the right lung. Ultrasound guided fine‐needle aspiration of the mass and subsequent cytologic examination exhibited a small round cell morphology. Immunohistochemistry done on the cell block revealed CD 99 and FLI‐1 positivity, confirming the diagnosis of ES. FISH supported the diagnosis, showing the EWSR1 rearrangement. Radiologic investigations ruled out a primary tumour elsewhere, confirming the diagnosis of primary pulmonary ES. The patient was started on chemotherapy.
