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.
我们报告了一例65岁女性患者，其有6个月的上腹部疼痛和消化不良病史。腹部和盆腔计算机断层扫描显示胃小弯处有一个强化的结节性病变以及一个大小不确定的4毫米淋巴结，这引发了对胃恶性肿瘤的担忧。上消化道内镜检查发现胃小弯处有一个10厘米的疑似恶性病变。组织病理学显示为梭形和小圆形蓝细胞肿瘤，免疫组化染色结果与尤因样肉瘤一致。经过多学科团队讨论，该患者被安排进行新辅助化疗并早期重新成像，随后考虑行胃切除术。本病例突出了原发性胃尤因样肉瘤的罕见诊断及对这种罕见疾病的治疗。
