Extra-adrenal pheochromocytomas, or paragangliomas, are rare tumours that may develop from extra-adrenal chromaffin cells, and most occur in the organ of Zuckerkandl. Extra-adrenal paraganglioma of the prostate is extremely rare. We report a 53-year-old man with hypertension and lower urinary tract symptoms, who was initially diagnosed with benign prostate hyperplasia. Computed tomography (CT) showed a large heterogenously enhancing mass in the prostate, imprinting the right distal ureter and urinary bladder. Before surgical intervention, CT-guided biopsy of the prostatic mass was performed and the result of histologic examination confirmed extra-adrenal paraganglioma. He underwent radical prostatectomy, partial cystectomy and right ureteroneocystostomy. The patient recovered and his blood pressure returned within normal range after surgical removal of the prostate tumour. In this article, we stress that the rarity of prostatic paraganglioma, preoperative localization and imaging-guided biopsy were useful in determining the surgical strategy.
肾上腺外嗜铬细胞瘤，即副神经节瘤，是一种罕见的肿瘤，可能由肾上腺外嗜铬细胞发展而来，多数发生于主动脉旁体。前列腺肾上腺外副神经节瘤极为罕见。我们报告一例53岁男性患者，有高血压及下尿路症状，最初被诊断为良性前列腺增生。计算机断层扫描（CT）显示前列腺有一个大的不均匀强化肿块，压迫右侧输尿管远端及膀胱。在手术干预前，对前列腺肿块进行了CT引导下活检，组织学检查结果证实为肾上腺外副神经节瘤。他接受了根治性前列腺切除术、部分膀胱切除术及右侧输尿管膀胱再植术。患者术后恢复良好，切除前列腺肿瘤后血压恢复正常。在本文中，我们强调前列腺副神经节瘤的罕见性，术前定位及影像引导下活检对确定手术策略很有用。
