尤文肉瘤是一种恶性圆细胞肿瘤，主要影响儿童骨骼。它也可能出现在骨外组织中，例如肺、肾和肝。尤文肉瘤的症状可能包括咳嗽、呼吸困难和胸痛。本报告详细介绍了一名 15 岁叙利亚男孩的病史，该男孩之前曾诊断出霍奇金淋巴瘤，并出现慢性肩痛。影像学检查显示，左肺尖有一个 80 毫米的肿块，计算机断层扫描引导活检后，通过组织病理学检查证实该肿块为尤文肉瘤。该患者接受了多个周期的化疗，随后对剩余肿块进行了手术切除。该病例凸显了肺部尤文肉瘤的罕见发生以及肩部疼痛而没有其他伴随症状的不寻常临床表现。© 2024。作者。

Ewing sarcoma is a malignant round-cell tumor that primarily affects bones in children. It can also arise in extraosseous tissues, such as the lung, kidneys, and liver. The presentation symptoms of Ewing sarcoma may include cough, dyspnea, and chest pain.This report details the history of a 15-year-old Syrian boy with a previous diagnosis of Hodgkin lymphoma who presented with chronic shoulder pain. Imaging studies revealed an 80 mm mass in the apex of the left lung, which was confirmed through histopathological examination to be Ewing sarcoma following a computed-tomography-guided biopsy. The patient received multiple cycles of chemotherapy and subsequently underwent surgical resection of the remaining mass.This case highlights the rare occurrence of Ewing sarcoma in the lung and the unusual clinical presentation of shoulder pain without other accompanying symptoms.© 2024.
