A 71-year-old white man with asymptomatic microscopic hematuria had a sessile tumor at the dome of the bladder containing benign prostatic glandular tissue. Benign prostatic polyps occur commonly in the prostatic urethra and bladder neck as vestigial remains of embryonic prostatic elements. Ectopic prostatic tissue elsewhere is rare and has not been described previously arising at the bladder dome. The origin of prostate glands in this unlikely location is unclear. The clinical course of ectopic prostatic polyps at any location is benign, although local recurrence has been reported.
一名71岁的白人男性，无症状性镜下血尿，膀胱顶部有一个带蒂肿瘤，含有良性前列腺腺组织。良性前列腺息肉常见于前列腺尿道和膀胱颈部，是胚胎前列腺成分的残余遗迹。其他部位的异位前列腺组织罕见，此前未见膀胱顶部出现的报道。前列腺腺体在这个不寻常位置的起源尚不清楚。尽管有局部复发的报道，但异位前列腺息肉在任何部位的临床过程都是良性的。
