Extraosseous Ewing’s sarcoma/primitive neuroectodermal tumor (ES/PNET) is an uncommon, aggressive, and malignant tumor with a poor patient outcome. Its occurrence in the lesser sac is a rare event and to the best of our knowledge, has not been previously described. The present case was clinically and radiologically misdiagnosed as a pancreatic tumor/gastrointestinal stromal tumor. Histopathology revealed a tumor with “small round cells” that were positive for CD99, confirming the diagnosis of ES/PNET. This report highlights the importance of considering Ewing’s sarcoma in the differential diagnosis of intraabdominal, extraintestinal masses.
