[Leydig cell tumor associated with epididymal cyst]. / Tumor de células de Leydig asociado a quiste epididimario.

Case report of a Leydig's cell testicular tumour associated to an epididymal cyst in a young adult. The literature revealed no relationship between both conditions. Review of diagnostic and therapeutical approaches.

[Rectal hemorrhage as the first manifestation of prostatic carcinoma]. / Rectorragia como primera manifestación de un carcinoma prostático.

OBJECTIVES: An uncommon case of prostatic carcinoma presenting as rectal hemorrhage is described. The diagnostic and therapeutic aspects are discussed and the importance of distinguishing this condition from rectal carcinoma is underscored. METHODS/RESULTS: The clinical features of a patient with invasive prostatic carcinoma presenting as rectal hemorrhage are described. CONCLUSIONS: Rectal involvement by invasive prostatic carcinoma should be suspected in patients consulting for a rectal pathology, particularly if the patient has a previous history of prostatism or carcinoma of the prostate. The incidence of rectal involvement by prostatic carcinoma has been reported to range from 1 to 11%.

[Paratesticular rhabdomyosarcoma. Diagnostic and therapeutic indications]. / Rhabdomyosarcome paratesticulaire. Attitude diagnostique et thérapeutique.

[Wilms' tumor in Cantabria. Review of our cases (1974-1990)]. / Tumor de Wilms en Cantabria. Revisión de nuestra casuística (1974-1990).

We reviewed the records of patients with genitourinary tumors that had been diagnosed and treated at the Section of Pediatric Surgery of Marqués de Valdecilla Hospital from 1974 to 1990. There were 14 such tumors. Of these, 12 (85.7%) were Wilm's tumor. This tumor type is the subject of the present study. Regarding its clinical features, 33.3% of the cases consulted for hematuria and an abdominal mass was the most common finding in the course of the disease (83%). We underscore the usefulness of CT and ultrasound in making the diagnosis. In the cases where these noninvasive imaging techniques were used, their efficacy rate was 100%. Together with IVP, these constitute the fundamental diagnostic tools. With regard to treatment, radical nephrectomy was performed in all cases and combined with radio and chemotherapy according to protocol. Pathological examination confirmed the diagnosis of Wilms' tumor in all the cases. Following the NWTS classification, there were 2 stage I,5 stage II, 2 stage III and 3 stage IV. Apart from tumor stage, the histological features significantly influenced the diagnosis. The survival rates for those with favourable or unfavourable histologic features were 70% and 36%, respectively.

[Retroperitoneal fibrosis in a patient treated with bromocriptine for a prolactinoma]. / Fibrose rétropéritonéale chez un patient traité par bromocriptine pour un prolactinome.

We present one case of retroperitoneal fibrosis occurring in a patient presenting with a prolactinoma identified five years previously and treated with bromocriptine since then. Bromocriptine, an ergot derivative with a dopaminergic action, seems to be the cause of the fibrosis in this patient.
