title: [Nephrogenic adenoma. Presentation of 7 cases].
abstract: Nephrogenic adenoma is a vesical lesion of uncertain pathogenesis. Histologically it is characterised by glandular-like aspects that take on the form of tiny tubules consisting of a single layer of cuboidal or columnar epithelium. The lesion was first described by Davis in 1949 and a year later Friedman and Kuhlembeck coined the term nephrogenic adenoma. Personal experience with seven cases of this lesion is reported here. Six of the seven cases occurred in the bladder, the remaining one in the prostatic urethra. Four patients reported prior surgery of the urinary ways, three suffered from recurrent cystitis, one had bladder stones while three were being followed up in our department for urothelial carcinoma. Diagnosis of nephrogenic adenoma was based on histopathological examination carried out on biopsy samples taken during urethrocystoscopy. The urothelial lesions were subjected to transurethral resection or endoscopic diathermocoagulation. All patients are being followed up and no recurrences have yet been reported.
