[Multilocular cystic nephroma. Preoperative diagnosis with CAT]. / Nefroma quístico multilocular: Diagnóstico preoperatorio mediante TAC.

We report a case of multilocular cystic nephroma in a 45-year-old female patient who had been referred for urological evaluation on detecting a mass in the left lumbar region. Patient work up included CT evaluation, which proved to be the most useful in making the diagnosis. The literature is reviewed with special reference to the nature of this lesion and the existing controversy on whether it is an embryonary tumor or a congenital malformation.

[Recurrent nephrogenic adenoma of the bladder: report of a case]. / Adenoma nefrogénico de vejiga recidividado: a propósito de un caso.

Nephrogenic adenoma of the bladder is a metaplastic lesion of the urothelium which is usually associated with infection or surgery. An additional case of nephrogenic adenoma that recurred one year following endoscopic treatment is described in a patient with a history of recurrent cystitis and hematuria. A review of the literature has shown that numerous cases have been reported in the past years. Thus, this disease entity is not as infrequent as it is considered to be.
