目的:本文旨在探讨回肠巨大原发性弥漫性大B细胞淋巴瘤的临床表现、影像学特点及诊治要点。方法:对延安市人民医院胃肠外科收治的回肠巨大原发性弥漫性大B细胞淋巴瘤合并肠梗阻1例患者进行病例回顾并复习相关文献。结果:回肠巨大原发性...目的:本文旨在探讨回肠巨大原发性弥漫性大B细胞淋巴瘤的临床表现、影像学特点及诊治要点。方法:对延安市人民医院胃肠外科收治的回肠巨大原发性弥漫性大B细胞淋巴瘤合并肠梗阻1例患者进行病例回顾并复习相关文献。结果:回肠巨大原发性弥漫性大B细胞淋巴瘤,发病率低,临床表现不典型;合并肠梗阻者,往往容易误诊及漏诊,最终确诊要需手术探查及病理。结论:回肠原发性弥漫性大B细胞淋巴瘤合并肠梗阻缺乏特异性临床表现,手术为首选治疗方法,需结合手术病理及免疫组化进行确诊。Objective: To explore the clinical manifestations, imaging characteristics, and key points of diagnosis and treatment of giant primary diffuse large B-cell lymphoma in the ileum. Method: A case review and literature review were conducted on a patient with giant primary diffuse large B-cell lymphoma of the ileum and intestinal obstruction admitted to the Department of Gastroenterology at Yan’an People’s Hospital. Results: The large primary diffuse large B-cell lymphoma of the ileum had a low incidence rate and atypical clinical manifestations;Patients with combined intestinal obstruction are often prone to misdiagnosis and missed diagnosis, and the final diagnosis requires surgical exploration and pathology. Conclusion: Primary diffuse large B-cell lymphoma of the ileum with intestinal obstruction lacks specific clinical manifestations, and surgery is the preferred treatment method. Diagnosis should be based on surgical pathology and immunohistochemistry.展开更多

文摘非霍奇金淋巴瘤(non-Hodgkin lymphoma,NHL)是临床常见的肿瘤类型,临床表现多样,确诊依赖组织活检,根据病灶起源可以分为结内和结外淋巴瘤。原发性胃肠淋巴瘤是结外淋巴瘤的常见部位,可以累及胃、小肠、结肠等,其中约50%~60%发生在胃部,病理类型以黏膜相关淋巴组织淋巴瘤和弥漫大B细胞淋巴瘤(diffuse large B-cell lymphoma,DLBCL)为主[1~3]。
