LEIOMYOMA OF THE BLADDER:A CASE REPORT

　60歳，女性．排尿困難を主訴に当科来院．膀胱鏡検査にて膀胱頸部左側に正常粘膜に覆われ膀胱内に突出する腫瘤を認めた．さらにCT，超音波検査などより膀胱粘膜下腫瘍を疑い手術を行った．腫瘤は容易に膀胱壁より剥離核出され，病理組織診では膀胱平滑筋腫であった．術後排尿困難は改善した．

A 60-year-old woman was admitted because of dysuria. Cystoscopic examination revealed a small hen egg sized mass covered with intact vesical mucosa and protruding from the left side of the bladder neck. Computed tomography and ultrasonography suggested a submucosal tumor of the bladder or cervical myoma of the uterus. Enucleation of the tumor through open sugery was performed and histopathological diagnosis was leiomyoma of the bladder without malignancy. Some clinical features of bladder leiomyoma are described from the review of reported cases.
