[Wilms tumor in adults. Report of a case]. / Tumor de Wilms del adulto. Aportación de un caso.

OBJECTIVE: Wilms' tumor or nephroblastoma is the most common renal tumor of childhood. The incidence in adults is rare, estimated at about 1% of all cases and approximately 200 cases have been described in the world literature. We report a new case of adult Wilms' tumor and realize a short review. METHODS/RESULTS: We describe a case of Wilms' tumor in a young male, aged 15 years, with associate genitourinary abnormalities. The patient underwent radical nepherctomy with postoperative chemotherapy. CONCLUSIONS: The Wilms' tumor in the adult population is exceptional, and the definitive diagnostic is based in the findings of the pathological analysis. The application of therapeutic protocolos for children to adults offers an smaller percentage of cure and poorer prognostic. Therapheutic protocolos more aggressive are necessary for increase the worse prognostic in the adult, but because of the rarity is difficult to define the most effective form of treatment.

[Prostatic adenocarcinoma associated with incidental intestinal carcinoid]. / Asociación de adenocarcinoma prostático y carcinoide intestinal incidental.

The association of a carcinoid tumour with non-endocrine urologic neoplasms is an infrequent finding. This paper contributes one case of multiple primary neoplasm where a prostatic adenocarcinoma coexists with an intestinal carcinoid tumour in a 63-year old asymptomatic patient. Diagnosis of prostate cancer was achieved during a screening for this conditions whereas the intestinal carcinoid tumour was found in the extension study.

[Antimicrobial prophylaxis in urology]. / Profilaxis antimicrobiana en urología.

UNLABELLED: Antimicrobial prophylaxis in surgery has proven to be effective in controlled randomized trials. Usage in Urology is known at least since the '30s although its effectiveness has only become known since 1979. METHODS: Review of literature related to surgical antibiotic prophylaxis, more specifically urological surgery, basically from 1991 to 1995, but without overlooking those papers that have become classics due to their impact. RESULTS AND CONCLUSIONS: Efficacy of antimicrobial prophylaxis in urological surgery is nowadays beyond all doubt. Usage is indicated in the presence of sterile urine and dosage must be short, in single dosis in the immediate pre-operative or within 24 hours after the procedure. However, there is a number of issues that deserve to be treated in more detail for better understanding. Those are the establishment of adequate prophylactic regimes in renal transplantation and the use of antimicrobials based on their pharmacokinetic characteristics to optimize the prophylactic purpose.

[A paratesticular myxoid liposarcoma as a simulator of a hernial process. A case report]. / Liposarcoma mixoide paratesticular como simulador de proceso herniario. Descripción de un caso.

OBJECTIVE: To describe a case of paratesticular liposarcoma in a 69-year-old male. The literature is briefly reviewed and the prognostic and therapeutic aspects are discussed. METHODS/RESULTS: The patient was submitted to surgery. Pathological analysis of the surgical specimen disclosed a myxoid liposarcoma with undifferentiated pleomorphic areas. Patient follow up has shown no recurrence or metastasis. CONCLUSIONS: This tumor type develops in scrotal soft tissue, slowly increasing scrotal size, and should be distinguished from inguinoscrotal hernia. Together with physical examination, ultrasonography is generally useful. Treatment is by radical orchiectomy through an inguinal approach; the role of adjuvant therapy remains unclear. It has a good prognosis, with frequent local relapses; metastatic spread is uncommon.

[Relationship between a benign fibroepithelial polyp and a pelvic nephroblastoma: report of a case]. / Relación entre un pólipo fibroepitelial benigno y un nefroblastoma piélico: a propósito de un caso.

The purpose of this paper is to report one case of left pyelic Wilms' tumour in a 17-year old male patient. Pre-operative diagnosis was complicated by a background of prior surgery on the same kidney due to a benign fibroepithelial polyp. The possible concomitences are analyzed while the relevance of an extensive pathoanatomical study to avoid possible diagnostic errors is emphasized.
