Mesonephric carcinoma is a tumor entity that rarely develops in the neck of the uterus and vaginal wall and is extremely unusual in the urinary bladder or paraurethral tissue. The tumors arise in the remnants of the wolffian or mesonephric duct. The malignant potential is considered to be lower than in tumors of the urethra with different histologic findings. Anterior pelvic exenteration is recommended in the literature as the treatment of choice. In the case described here, the tumor presented as a space-occupying lesion in a urethral diverticulum exhibiting striking clinical features of macrohematuria and urinary retention with subvesical obstruction of the urethra. In accordance with reports in the literature, cystectomy was performed and a Kock pouch constructed for urinary diversion. Tumors occurring in a diverticulum-and in this case manifesting as the rare tumor form of mesonephric carcinoma-should always be included in the differential diagnosis of macrohematuria in women.
中肾管癌是一种肿瘤实体，很少发生于子宫颈和阴道壁，在膀胱或尿道旁组织中极为罕见。肿瘤起源于中肾管或沃尔夫管的残余部分。与具有不同组织学表现的尿道肿瘤相比，其恶性潜能被认为较低。文献中推荐前盆腔脏器清除术作为首选治疗方法。在此描述的病例中，肿瘤表现为尿道憩室内的占位性病变，具有肉眼血尿和尿道膀胱下梗阻导致尿潴留的显著临床特征。根据文献报道，进行了膀胱切除术并构建了Kock袋用于尿液改道。发生于憩室内的肿瘤——在本例中表现为罕见的中肾管癌肿瘤形式——在女性肉眼血尿的鉴别诊断中应始终予以考虑。
