title: Nephrogenic adenoma in a urethral diverticulum.
abstract: Nephrogenic adenoma (NA) is a rare finding that represents metaplasia of the urothelium. We present a case of a 46-year-old woman who presented with a symptomatic anterior vaginal wall cyst that was found to be an NA within a urethral diverticulum. Although this remains an infrequently reported entity in the literature, prevalence has been shown to be higher in consecutive case series than what may be presumed by the rarity of case reports in clinical literature. Nephrogenic adenoma within a urethral diverticulum may represent an under-recognized entity which needs to be carefully distinguished from clear cell adenocarcinoma occurring within urethral diverticula. We discuss salient clinical features of NA occurring within a urethral diverticulum and describe a review of literature of published cases to date.
