Creation of an ileal conduit is associated with complications. A few cases have been reported on tumor development in an ileal conduit; diffuse large B-cell lymphoma originating from an ileal conduit is extremely rare.
A 62-year-old Japanese man who had undergone radical cystectomy and ileal conduit diversion 6 years previously presented with a whitish bulge that had developed on the surface of the ileal conduit during follow-up visit. Mass biopsy was performed and the histological diagnosis was diffuse large B-cell lymphoma. Positron emission tomography showed no metastatic lesions. We attempted chemotherapy because the tumor cells tested positive for CD20; after six courses of a regimen involving rituximab, cyclophosphamide, doxorubicin, vincristine, and prednisone; diffuse large B-cell lymphoma of the ileal conduit resolved gradually. The patient is alive and remains free from the diagnosed diffuse large B-cell lymphoma.
We reported an extremely rare case of diffuse large B-cell lymphoma originating from the ileal conduit created after radical cystectomy.
回肠膀胱术常伴有并发症。有少数关于回肠膀胱内肿瘤发生的病例报道;起源于回肠膀胱的弥漫性大B细胞淋巴瘤极为罕见。
一名62岁的日本男性,6年前接受了根治性膀胱切除术及回肠膀胱术,在随访期间,其回肠膀胱表面出现了一个白色隆起。进行了肿块活检,组织学诊断为弥漫性大B细胞淋巴瘤。正电子发射断层扫描显示无转移病灶。由于肿瘤细胞CD20检测呈阳性,我们尝试进行化疗;在接受了六个疗程包含利妥昔单抗、环磷酰胺、阿霉素、长春新碱和泼尼松的方案治疗后,回肠膀胱的弥漫性大B细胞淋巴瘤逐渐消退。患者目前存活,且未再出现已确诊的弥漫性大B细胞淋巴瘤。
我们报告了一例极为罕见的起源于根治性膀胱切除术后所造回肠膀胱的弥漫性大B细胞淋巴瘤病例。
