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

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.
