[Mucinous adenocarcinoma. Unusual prostatic tumor]. / Adenocarcinoma mucinoso. Una tumoración prostática poco frecuente.

We report a case of mucinous adenocarcinoma of the prostate. A 80 years-old patient was diagnosed with a transrectal multiple biopsy. We comment on the special histological patterns of the tumor as well as the established criterion for an appropriate diagnosis.

[Bladder adenocarcinoma. Presentation of 3 new cases]. / Adenocarcinoma vesical. Presentación de tres nuevos casos.

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.

[Multilocular cyst of the kidney: clinico-pathologic considerations]. / Quiste multilocular renal: consideraciones clínico-patológicas.

Multilocular Renal Cyst is a variety contained within the Spectrum of Renal Embryonic Tumors, presenting much confusion relating to its terminology, histology, clinical aspects, etc. We have carried out a review of this subject through bibliographical compilation of the cases published between 1976-86, and close analysis of the series thus far published. The diagnostic criteria described by Boggs and Kimmeslstiels in 1956, which classify this entity separate from other varieties of R.E.T. and similar ones. This pathological state can be seen in both children and adults, and it is characterized by its unusual appearance, clinical silent in the adults and in the child it appears as an abdominal mass. This pathology lacks specific diagnostic tests as well as the assistance rendered by clinical, radiological or ultrasound studies, it will depend on a correct preoperative diagnosis, an extremely difficult task to achieve, or on a diagnostic approximation geared to avoid in the child population the implementation of coadjuvant measures to surgery that will no doubt give rise to unwanted situations in the long run. The treatment of this pathology is strictly surgical and must be preceded by an extremely conservative approach. Tumorectomy or Partial Nephrectomy is curative and sufficient. From the anatomopathological study of the surgical sample, the correct diagnosis may be inferred.
