Inflammatory myofibroblastic tumor (IMT) is a rare, benign spindle cell neoplasm of the urinary bladder with a presentation concerning a malignant disease. Oftentimes, these tumors pose a diagnostic dilemma because of a significant overlap with malignant spindle cell tumors in terms of clinical presentation, gross findings, and immunohistopathologic profile. A 28-year-old female presented to us with gross hematuria. Upon work up, the presence of a bladder mass was noted. Cystoscopy and transurethral resection of bladder tumor were done and histopathologic results revealed an IMT. Partial cystectomy was then performed for complete surgical resection.
炎性肌成纤维细胞瘤（IMT）是一种罕见的膀胱良性梭形细胞瘤，其表现易被误诊为恶性疾病。通常情况下，这些肿瘤在临床表现、大体检查结果和免疫组织病理学特征方面与恶性梭形细胞瘤有显著重叠，因此常造成诊断困境。一名28岁女性因肉眼血尿前来就诊。经检查，发现膀胱有肿物。进行了膀胱镜检查和经尿道膀胱肿瘤切除术，组织病理学结果显示为IMT。随后进行了部分膀胱切除术以完成手术切除。
