RESUMEN
Renal multilocular cyst continues to be, up-to-date, an entity of unknown pathoetiology. In many occasions, particularly in children, it has been mistaken with a partially differentiated cystic nephroblastoma. Due to the absolute benignancy of the multilocular cyst and the likelihood of preserving the renal parenchyma, we consider of interest to contribute a brief review of the current pathoetiological theories and clinical development, as well as our experience in this disease.

Fibroepithelial polyp of the trigone of bladder conditioning an occlusive syndrome at the bladder cervix level causing secondary multidiverticular bladder with ureterohydro-nephrosis and chronic bilateral pyelonephritis. Besides the rare vesical location for the fibroepithelial polyps, the case also presents some atypical stromal cells.

Three additional cases of primary adenocarcinoma of the bladder, an uncommon tumor type, seen at our department during the past years are described. These may arise from urachal remnants or metaplastic changes occurring in bladders with cystitis cystica or glandularis. Clinically, their behaviour is not unlike the rest of the infiltrating urothelial tumors. Treatment is by partial cystectomy for urachal adenocarcinoma and radical cystectomy for those arising from other sites of the bladder. Radio- and chemotherapy have a very limited efficacy in this tumor type.
