A previously healthy 44-year-old male was admitted with the chief complaint of intermittent gross hematuria. On initial ultrasonographic and CT examination, a grossly protruding intravesical tumor was noted and, under the impression of a malignant bladder tumor, transurethral resection was performed. The histological findings were spindle cells with elongated cytoplasm with rare mitotic figures distributed in myxoid stroma, consistent with diagnosis of inflammatory pseudotumor of the bladder. The benign nature of this tumor warrants conservative surgical management, usually consisting of transurethral resection or partial cystectomy. No reports of metastasis have been reported following complete excision. Therefore, any suspicion and recognition of this entity is imperative to avoid performing an irreversible radical procedure.
一名既往健康的44岁男性因间歇性肉眼血尿为主诉入院。初次超声和CT检查时，发现膀胱内有一个明显突出的肿瘤，在考虑为恶性膀胱肿瘤的情况下，进行了经尿道切除术。组织学检查发现为梭形细胞，胞质细长，有罕见的有丝分裂象，分布于黏液样基质中，符合膀胱炎性假瘤的诊断。该肿瘤的良性性质需要采取保守的手术治疗，通常包括经尿道切除术或部分膀胱切除术。完全切除后尚无转移的报道。因此，对该实体的任何怀疑和认识对于避免进行不可逆转的根治性手术至关重要。
