膀胱内异位前列腺增生组织伴慢性炎症1例报告并文献复习

Hyperplasia in ectopic prostate tissue with chronic inflammation in the bladder:A case report and literature review

目的:提高对异位前列腺增生组织伴慢性炎症的认识,探讨其发生机制及诊疗方法。方法:收治的1例膀胱内异位前列腺组织患者的临床资料进行归纳分析,并进行文献复习。结果:本例患者是71岁老年男性,因影像学发现膀胱占位和血清PSA异常升高,同期行经会阴前列腺穿刺活检术及经尿道膀胱肿物电切术。术中见一孤立、光滑的实性结节样肿物位于膀胱内输尿管间嵴正中位置。术后前列腺穿刺活检标本和膀胱内肿物标本病理均提示良性前列腺增生组织,伴局部慢性炎症。术后随访6个月,未见复发。结论:膀胱内异位前列腺增生组织临床上很少见,同时伴慢性炎症的病例更加罕见。诊断靠影像学检查,确诊需依据病理。手术完整切除是目前首选的治疗方案。

Objective:To improve the understanding of ectopic prostatic hyperplasia tissue with chronic inflammation,and to explore its occurrence mechanism and diagnosis and treatment.Methods:The clinical data of a patient with ectopic prostate tissue admitted to our hospital were analyzed and the literature was reviewed.Results:This paper reports a 71 year old male patient with benign hyperplasia in ectopic prostate tissue with chronic inflammation in bladder.This patient underwent a transperineal biopsy of prostate and transurethral resection of bladder mass because the imaging examination indicated a space-occupying mass and abnormally elevated blood prostate-specific antigen(PSA).During the operation,an isolated,smooth solid nodule was observed in the middle of the interureteric ridge in the bladder.Postoperative pathological examination of prostate biopsy specimen and bladder mass specimen showed benign hyperplasia in prostate tissue accompanied with local chronic inflammation.The patient received the postoperative follow-up for half a year,and no recurrence was observed.Conclusion:Intravesical ectopic prostatic hyperplasia tissue is clinically rare,and cases with chronic inflammation are even more rare.Diagnosis depends on imaging examination,and diagnosis is based on pathology.Surgical complete resection is currently the preferred treatment option.
