To present a new case of nephrogenic adenoma of the bladder and to review the current concepts on the etiopathogenesis of this lesion.
Seventy years old female with repetitive haematuria who was diagnosed as having a nephrogenic adenoma of the bladder which was extirpated by cold biopsy forceps. No tumoral relapse was detected after 16 months of follow up.
In the light of the present knowledges, the origin of nephrogenic adenoma is a phenomenon of urothelial metaplasia due to a chronic irritative stimulus wich would lead a cellular proliferation with potentialities to originate mesonephric tissues and which starting point could be on not completely involutioned mesonephric cellular rests and/or on de-differentiated mature urothelial cells.
报告一例膀胱肾源性腺瘤新病例,并回顾目前关于该病变病因发病机制的概念。
一名70岁女性,反复血尿,被诊断为膀胱肾源性腺瘤,通过冷活检钳切除。随访16个月后未发现肿瘤复发。
根据目前的知识,肾源性腺瘤的起源是一种尿路上皮化生现象,由于慢性刺激导致细胞增殖,有可能产生中肾组织,其起始点可能是未完全退化的中肾细胞残余和/或去分化的成熟尿路上皮细胞。
