Abstract

We report the case of a 79-year-old woman with primary lymphoma of mucosa-associated lymphoid tissue (MALT) in the urinary bladder. The patient, with urinary frequency, urgency and suprapubic pain had several emergency room visits due to recurrent urinary tract infection. Both sonogram and cystoscopy identified bladder tumors near the bladder neck. An abdominal contrast-enhanced computed tomography scan revealed a polypoid lesion on the anterior bladder wall without enlarged lymph nodes. Transurethral resection of the bladder tumor was conducted. The pathology report confirmed extranodal marginal zone MALT lymphoma. The clinical stage was IEA. Follow-up imaging reported residual bladder tumors, prompting adjuvant radiotherapy. The patient was treated successfully and was disease-free at the 9-month follow-up visit. Primary lymphoma is an uncommon pathological subtype. Its clinical and radiological differentiation from urothelial carcinoma (UC) can be challenging, but treatment strategies differ significantly. A definitive diagnosis relies on histopathology and immunohistochemistry. Typically, bladder lymphoma has a favorable prognosis, but further research is required to identify the optimal treatment.

模仿复发性尿路感染的膀胱粘膜相关淋巴组织(MALT淋巴瘤)原发性淋巴瘤:病例报告和文献综述。
我们报告了一例膀胱粘膜相关淋巴组织(MALT)原发性淋巴瘤的 79 岁女性病例。患者伴有尿频、尿急和耻骨上疼痛,曾因反复尿路感染多次到急诊就诊。超声波检查和膀胱镜检查均发现膀胱颈部附近有膀胱肿瘤。腹部造影剂增强计算机断层扫描显示,膀胱前壁有息肉样病变,但无肿大淋巴结。患者接受了经尿道膀胱肿瘤切除术。病理报告证实为结节外边缘区 MALT 淋巴瘤。临床分期为 IEA。随访影像报告显示有膀胱肿瘤残留,因此需要进行辅助放疗。患者接受了成功的治疗,并在9个月的随访中痊愈。原发性淋巴瘤是一种不常见的病理亚型。它与尿路上皮癌(UC)的临床和放射学鉴别具有挑战性,但治疗策略却大相径庭。明确诊断有赖于组织病理学和免疫组化。通常情况下,膀胱淋巴瘤的预后良好,但仍需进一步研究以确定最佳治疗方法。
