[Fibroepithelial polyp of the urethra in an adult].

We present the case of a fibroepithelial polyp of the prostatic urethra in a forty-five year old patient. This type of polyp is rare in the adult. The principal symptoms which the patient presented were haematuria and an intermittent reduction in micturitional flow. Endoscopic images of the tumour are shown and certain details of its histology; this is a polypoid lesion of loose connective tissue covered by typical urothelium, with occasional fascicles of smooth muscle, no prostatic-type glandular structures and no appreciable inflammatory component.

[Adrenal ectopy in epididymis].

OBJECTIVE: To report a case of ectopic adrenal in the epididymis. METHODS: A 17-year-old male consulted for a left varicocele and complaints referred to the right epididymis a year and a half after an episode of acute epididymitis. A nodule was excised from the epididymis. RESULTS: The pathological analysis showed an 0.4 cm nodule comprised of adrenocortical tissue. CONCLUSIONS: Ectopic adrenal cortical tissue is a benign lesion. Although routine search for this lesion is not indicated, it should be resected for histological analysis and differential diagnosis when it is found during a surgical procedure in this area.

[Non-functional renal paraganglioma associated with carotid paraganglioma and appendicular mucocele].

OBJECTIVE: A case of nonfunctional renal paraganglioma associated with appendicular mucocele and metachronic carotid paraganglioma is presented. METHODS/RESULTS: A 68-year-old patient consulted for abdominal pain. Patient evaluation with US, CT and opague enema showed an elongated mass that compromised the cecum and a solid mass in the right kidney. The patient underwent appendectomy and radical right nephrectomy. The anatomopathological findings showed an appendicular mucocele and renal paraganglioma. The postoperative hormone analyses were normal. A carotid paraganglioma was removed 8 months later. CONCLUSIONS: Renal tumors arising from neural crest cells are uncommon. To our knowledge, this is the third case of nonfunctional renal paraganglioma reported in the literature. The associated appendicular mucocele was an incidental finding.

[Adrenal tuberculosis. Diagnosis using polymerase chain reaction].

OBJECTIVE: To present a case of a patient suffering from adrenocortical insufficiency (Addison's disease) and to demonstrate the utility of the polymerase chain reaction (PCR) in the diagnosis of adrenal cortex tuberculosis. METHODS/RESULTS: Herein we describe a patient with Addison's disease who had developed pulmonary tuberculosis a few years earlier. CT and PCR test were utilized in making the diagnosis. CONCLUSION: Although adrenocortical tuberculosis is uncommon today, it must be considered when evaluating adrenocortical insufficiency, especially if the patient has or has had tuberculosis. Although Mycobacterium tuberculosis might not be demonstrated by bacteriologic techniques, PCR can be useful in making the etiological diagnosis.

[Blind ureter ending in ejaculatory duct. Report of a case].

OBJECTIVES: Herein we describe a case of an extremely uncommon malformation of the genitourinary system in a patient who had consulted for epididymitis. METHODS: Patient evaluation included radiological examination, IVP, US, CT and DVG The latter method was essential in the diagnosis of the malformation. RESULTS: The findings indicated left renal agenesis with blind left ureter opening to the ipsilateral ejaculatory duct, with severe deformity of the left seminal vesicle and ejaculatory duct. CONCLUSIONS: Since the patient has no important symptoms at the present time, contrary to the widely accepted approach, surgery has not been performed due to the risk of causing an iatrogenic lesion.

[Acute adrenal hemorrhage and contralateral renal adenocarcinoma].

We report a case of spontaneous retroperitoneal hematoma from rupture of the right adrenal in a patient with asymptomatic left renal adenocarcinoma that had been incidentally detected during evaluation to determine the cause of the retroperitoneal hematoma.

[Wilms' tumor in Cantabria. Review of our cases (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.

[Epithelioid hemangioendothelioma of penis].

A case of EH of the penis in a sixtyfour-year-old patient is described. This is a rare--in this location--vascular tumor of borderline malignant potential between hemangioma and angiosarcoma. Local excision of the tumor with a cut-off of normal tissue and careful follow-up of the patient is the accepted procedure. Immunohistochemistry is essential for the diagnosis.

[Stenosis of the ileal loop in a patient with Bricker type urinary diversion].

Stenosis of the ileal loop itself in the urinary diversion performed with the technique described by Bricker is uncommon, particularly in adults, and nowadays is basically managed through non-invasive methods. This paper contributes one case of stenosis of the ileal loop in a patient with urinary diversion performed with Bricker's technique, which was treated by partial resection of the ileal loop, since use of non-invasive techniques was not possible due to technical hindrances. The pathoanatomical study showed the different etiopathogeny of this type of stenosis relative to others related to the ileal loop (stoma and ureteroileal attachment stenosis). A review is made of the etiopathogeny, signs and symptoms, diagnosis and treatment of this type of stenosis. Occurrence of stenosis as late complication has lead us to consider the convenience for late revisions in this type of surgery.
