Abstract：
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.
摘要：
目的：提高对异位前列腺增生组织慢性炎症的认识,并探讨其发生机制和诊治方法。方法：分析我院收治的1例异位前列腺组织患者的临床资料并复习文献。结果：本文报道1例71岁男性异位前列腺组织良性增生伴膀胱慢性炎症患者。该患者接受了经会阴前列腺活检和经尿道膀胱肿块切除术，因为影像学检查显示占位肿块和血液前列腺特异性抗原（PSA）异常升高。在操作过程中,一个孤立的,在膀胱输尿管间脊中部观察到光滑的实性结节。前列腺活检标本及膀胱肿块标本术后病理检查显示前列腺组织良性增生伴局部慢性炎症。术后随访半年，没有观察到复发。结论：膀胱内异位前列腺增生组织临床少见,慢性炎症病例更为罕见。诊断取决于影像学检查，诊断是基于病理学。手术完全切除是目前首选的治疗选择。
