[Verrucous carcinoma of the penis or Buschke-Löwenstein tumor. A rare tumor. Apropos of a case]. / "Carcinoma verrucoso de pene o tumor de Buschke-Löwenstein". Una tumoración poco frecuente. A propósito de un caso.

An additional case of verrucous carcinoma of the penis is described. This tumor type accounts for approximately 5% of squamous carcinomas of the penis. Today penile verrucous carcinoma is widely considered to be the same tumor as that described by Buschke and Löwenstein in 1925. The histological and clinical features as well as the therapeutical aspects of this tumor type are briefly reviewed herein.

[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.

[Papillary necrosis and formation of fungal balls in a patient with AIDS: a clinical case and brief review]. / Necrosis papilar y formación de pelotones de hongos en paciente afecto de SIDA: caso clínico y breve revisión.

An AIDS case, with a Candida urinary infection causing papillary necrosis and accompanied by occurrence of fungal lumps is reported. The paper remarks on the incidence and peculiarities of urinary affectation in these patients, emphasizing the usefulness of percutaneous nephrostomy as a diagnostic, and above all as a therapeutic procedure, in cases of expanded urinary tract.

[Inverted papilloma or inverted urothelial carcinoma. A problem not yet resolved in its totality. Contribution of two new cases to the literature]. / Papillome inversé ou carcinome urothélial inversé. Un problème qui encore aujourd'hui n'a pas été résolu dans sa totalité. Apport de deux nouveaux cas à la littérature.

We present two case of inverted vesical papillomas, one of a trabecular histology and the other glandular, which--in view of the appearance in the last few years of inverted papillomas coexisting alongside other urothelium tumorous states, recurring and even malignant inverted papillomas--raise the possibility of them being considered as superficial urothelium carcinomas. We propose the use of post-surgical endo-vesical chemotherapy, above all in the patients affected by the trabecular variety of inverted papillomas, due to their high indices of recurrence and high possibilities of malignancy.

[A new case of multilocular cyst]. / Un nuevo caso de quiste multilocular.

We report another case of multilocular cyst of the kidney. We underscore the current theory on the neoplastic and not cystic origin of this disease entity. Attention is drawn to the confusion arising from a wide variety of terms (17) used to refer to this disease entity. Its clinical features, diagnosis, and treatment are briefly discussed. We highlight the need to follow currently available diagnostic criteria in diagnosing multilocular cyst of the kidney.

[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.
