前列腺炎症性肌纤维母细胞瘤一例报道并文献复习

Inflammatory myofibroblastic tumor of the prostate: a case report and review of the literatures

目的探讨前列腺炎症性肌纤维母细胞瘤(IMT)的诊治方案。方法前列腺IMT是一种罕见的交界性肿瘤,其临床特点、影像学特征无特异性,诊断困难,主要依靠病理诊断。回顾性分析1例前列腺IMT患者的临床资料并复习相关文献。患者,男性,62岁,间歇性尿频、尿痛、排尿困难4年,加重1个月。CT提示前列腺囊性占位,两次行经尿道前列腺电切术(TURP),术后病理证实为前列腺炎症性肌纤维母细胞瘤。结果首次TURP术后两月前列腺炎症性肌纤维母细胞瘤复发,行二次TURP术后随访14个月,患者排尿正常,无复发和转移。结论前列腺IMT的诊断主要依靠病理,有复发可能,手术切除肿瘤是首选方法,术后随访,复查极为重要。

Objective To investigate the diagnosis and treatment of inflammatory myofibroblastic tumor （IMT） of the prostate. Methods Prostate IMT is a rare borderline tumor, of which clinical features, imaging features are non-speclfic, its diagnosis is difficult, and rely mainly on the pathological diagnosis. The clinical data of a case of IMT of the prostate were analyzed retrospectively and relevant literatures were reviewed.

Two sequential TURP surgeries, pathologically confirmed as inflammatory myofibroblastic tumor of the prostate. Results Two months after the first TURP, the inflammatory myofibroblastic tumor of the prostate recurrence. Followed up for 14 months, the patient sustained normal micturition, without recurrence or metastasis after the second TURP. Conclusions The diagnosis of IMT of prostate relies on the pathologic, and the recurrence, surgical resection is the preferred method, and postoperative follow-up is extremely important.
