摘　　要：异位前列腺临床罕见。本文报道1例男性患者,因体检发现盆腔肿物20d就诊。超声、CT、MRI检查提示盆腔肿物,大小约4cm×5cm,总前列腺特异性抗原(tPSA)6.09ng/ml,游离PSA1.97ng/ml。行B超引导下前列腺和肿物穿刺活检,病理检查提示前列腺良性增生,免疫组化染色检查P504S(弱+),34βE12(+);盆腔肿物为前列腺组织,P504S(-),34βE12(+),考虑盆腔肿物为异位前列腺。尽管罕见,异位前列腺也应被考虑为盆腔肿瘤的鉴别诊断之一。Ectopic prostate is rare.This paper reports a case of a male patient who was found a mass in the pelvis for 20 days during physical examination.Urinary ultrasound,CT scan and MRI showed a pelvic mass that was about 4 cm×5 cm in size.Serum total prostate specific antigen(tPSA)was 6.09 ng/ml,and free PSA(fPSA)was 1.97 ng/ml.B-ultrasonic guided biopsy of the prostate and the mass was performed.Pathological findings suggest benign prostatic hyperplasia,weakly positive P504S and positive 34βE12.Pelvic mass is the prostate tissue with negative P504S and positive 34βE12.Finally,the ectopic prostate was diagnosed.Although it is rare,ectopic prostate should also be considered as a differential diagnosis of the pelvic tumor.
