膀胱炎性肌纤维母细胞瘤4例报道及文献复习

目的:复习文献并探讨膀胱炎性肌纤维母细胞瘤(inflammatory myofibroblastic tumor,IMT)的临床表现、病理特点、诊断及治疗方法。方法:回顾分析4例膀胱IMT患者的资料,并结合文献进行分析。结果:4例术前均行B超及膀胱镜检查并活检,3例病理诊断为膀胱炎性病变可能,膀胱肿瘤不能排除;1例报告为膀胱IMT。4例均行膀胱部分切除,术后病理确诊为膀胱IMT。3例随访至今未见复发,1例随访7个月后失访。结论:膀胱IMT临床特征酷似膀胱肿瘤,确诊主要依靠病理学检查,手术是治疗本病的主要方法。

Bladder inflammatory myofibroblastic tumor:report of 4 cases and review of the literatures

Objective：To investigate the clinical and pathological characteristics,the treatment and prognosis of inflammatory myofibroblastic tumor（IMT）by reviewing the literatures.Methods：The clinical data and pathological characteristics of 4 cases of IMT treated were analyzed retrospectively,and the literatures were reviewed.Results：All the 4 cases received supersonic wave and cystoscopy.Three cases were diagnosed as cystitis possible,and bladder tumor could not be precluded;1 case was reported to be bladder IMT.Four cases underwent partial resection of the bladder and all were confirmed to be IMT by pathology.Up to now,3 cases had no relapse,and 1 case was followed up no longer than 7 months.Conclusions：The clinical feature of bladder IMT resembles that of bladder tumor.Final diagnosis relies on immunohistochemical method.Surgical operation is the best procedure for the treatment of the disease.
