Abstract

We report the case of a 65-year-old female who presented with a 6-month history of epigastric pain and dyspepsia. Computed tomography of the abdomen and pelvis showed an enhancing nodular lesion and an indeterminate 4 mm lymph node on the lesser curvature of the stomach raising concerns for gastric malignancy. Upper gastrointestinal endoscopy revealed a 10 cm malignant appearing lesion along the gastric lesser curvature. Histopathology demonstrated spindled and small round blue cell tumor with immunohistochemistry staining consistent with Ewing-like sarcoma. After multidisciplinary team discussion the patient was arranged for neoadjuvant chemotherapy with early re-imaging, followed by consideration of gastrectomy. This case highlights the unusual diagnosis of primary gastric Ewing-like sarcoma and the management of this rare condition.

Keywords: Ewing sarcoma; Ewing sarcoma of the stomach; Ewing-like sarcoma; Extraskeletal Ewing sarcoma; gastric Ewing sarcoma.
