[Extra-adrenal pheochromocytoma. Report of a case].

OBJECTIVE: To report a case of extraadrenal pheochromocytoma with special reference to the diagnostic and therapeutic aspects. METHODS: A case of extraadrenal pheochromocytoma in a 20-year-old female with severe hypertension is presented. The clinical and biochemical aspects are reviewed with special reference to the diagnostic imaging methods. RESULTS: Plasma noradrenaline and urinary normetanephrine levels were elevated. CT and MRI showed a well-defined mass, 6 cm in diameter, adjacent to the left kidney, abdominal aorta and psoas muscle. Angiography demonstrated a high vascularization in the area of the tumor. MIBG scintigraphy revealed a well-defined mass, but no other distant lesions. Surgical treatment was performed with preoperative alpha and beta adrenergic blockade. Currently the patient has a normal blood pressure and catecholamine levels, with no evidence of lesions on the MIBG scintiscan. CONCLUSIONS: Plasma catecholamine and urinary normetanephrine levels levels confirmed the presumptive diagnosis of pheochromocytoma. MIBG is the technique of choice for the localization of the mass and suspected metastases. CT, MRI and angiography demonstrated the anatomic relationships of the tumor. The best results are achieved with complete resection and preoperative adrenergic blockade.

[Multilocational cystic nephroma. Review of a case with reference to echographically observed changes].

OBJECTIVE: To describe an additional case of multilocular cystic nephroma, with special reference to the sonographic features of a renal cystic lesion. METHODS: The clinical and radiological features of a kidney tumor in a 61-year-old female patient were retrospectively analyzed. RESULTS: The preoperative diagnosis was that of a complex multicystic renal mass suggestive of a renal carcinoma. Radical nephrectomy was performed; histopathological analysis of the surgical specimen disclosed a multilocular cystic nephroma. An ultrasound scan 18 months earlier had demonstrated a simple renal cyst in the same site. CONCLUSIONS: Multilocular cystic nephroma is a tumor that is difficult to diagnose preoperatively. Making an accurate differential diagnosis is of interest, since it will permit conservative treatment. The case described herein supports the hypothesis with regard to the pathogenesis of this lesion, since it had previously showed sonographic features of a simple renal cyst.

[Hemangioma of the spermatic cord. Presentation of a case with review of the literature].

OBJECTIVE: To describe a rare variety of spermatic cord tumor, with special reference to the differential diagnosis. The literature is briefly reviewed. METHODS: The clinical and pathological features of a tumor located in the right inguino-scrotal region of a 27-year-old male patient are described. RESULTS: The preoperative evaluation disclosed an irregular mass in the right hemiscrotum that was unconnected to the testis. The patient underwent orchidectomy and resection of the tumor. Pathological analysis of the surgical specimen revealed a hemangioma of the spermatic cord. CONCLUSIONS: Hemangioma of the spermatic cord is a very uncommon tumor, it is a slow growing, indolent, benign scrotal lesion that must be distinguished from other paratesticular masses or tumors with similar clinical features. Ultrasound and other diagnostic imaging techniques are not useful in making the preoperative differential diagnosis.

[Transitional cell bladder carcinoma in patients younger than 40 years of age].

OBJECTIVE: The clinical and pathological characteristics of bladder cancer in young patients were analyzed to determine if patients with bladder cancer under the age of 30 have a better prognosis than older adults and if transitional cell carcinoma of the bladder in patients aged 30 to 40 years has a similar behaviour to that observed in the higher risk population. METHODS: A retrospective review of transitional cell carcinoma of the bladder in patients less than 40 years old that had been treated between January, 1993 to August, 1997 was undertaken. RESULTS: We found 8 patients (5 men and 3 women) with urothelial tumor, accounting for an incidence of 4%. Four cases were diagnosed and staged TaG1, 2 T1G1 and 2 T1G2. Recurrence was observed in one case (12.5%) and progression in none. CONCLUSIONS: Transitional cell carcinoma of the bladder in patients under the age of 40 is usually associated with low grade and low stage tumors. The foregoing finding is certainly observed in those aged less than 30 years old. Bladder cancer is relatively rare in this age group, although we have found a higher incidence than that reported elsewhere. Treatment and follow-up depend on tumor grade and stage, regardless of age.

[Perineal tuberculous abscess. Presentation of a clinical case].

OBJECTIVE: To describe a case of perineal abscess caused by Koch's bacillus in a patient with a history of bladder tumor. METHODS/RESULTS: The patient described herein had consulted at the emergency services for perineal abscess. He had previously undergone transurethral resection of a bladder tumor and had received prophylactic intravesical BCG instillation thereafter. A culture of the exudate led to the diagnosis of tuberculosis, with no microbiological relation to BCG therapy. During the course of the disease, the patient developed a urethrocutaneous fistula which resolved after specific medical treatment. CONCLUSIONS: In a patient with clinical features of tuberculosis and a recent history of exposure to BCG, it does not necessarily follow that this bacillus is the cause of the tuberculosis. Furthermore, not all tuberculous fistulas progress to chronicity or require surgical treatment.

[Bilateral obstructive uropathy secondary to encrusted cystitis. Report of a case].

OBJECTIVES: Bilateral urinary obstruction is usually secondary to tumors or bilateral lithiasis. A rare case of encrusted cystitis causing bilateral hydronephrosis is described. METHODS/RESULTS: A 70-year-old woman presented with severe dysuria and vesical tenesmus. She had previously undergone pelvic surgery and received radiotherapy for a gynecological tumor. She was diagnosed as having encrusted cystitis. Treatment with urinary acidification and antibiotics achieved complete radiological and functional recovery. CONCLUSIONS: Some cases of urinary obstruction can be managed conservatively. An accurate diagnosis is necessary to avoid surgery in these cases.

[Adenomatoid tumor of the epididymis. Report of a new case].

OBJECTIVES: To report on an additional case of adenomatoid tumor of the right epididymis, a rare benign intrascrotal mass. METHODS/RESULTS: A 41-year-old man consulted for severe scrotal pain. Physical examination disclosed a mass in the right epididymis which was confirmed by scrotal ultrasound. A right orchidectomy was performed. Histological analysis of the surgical specimen disclosed a benign adenomatoid tumor of the epididymis. CONCLUSIONS: Although most scrotal solid masses are malignant tumors, those arising in the epididymis are frequently benign; therefore a conservative approach is recommended.

[Epidermoid cancer of the penis: our experience].

OBJECTIVES: We reviewed our series of epidermoid penile cancer to determine the predictive index of lymph node invasion and the incidence of phimosis in these patients. METHODS: We reviewed the records of 11 patients with epidermoid cancer of the penis. Six patients had been evaluated according to a protocol that included preoperative biopsy of the lesion, penile and abdominal ultrasound evaluation, CT and diagnostic lymphadenectomy for those cases suspected as having lymph node invasion. The predictive index (PI) was determined in relation to the grading of cell differentiation (G) and tumor stage (S) [PI = G+T] and the incidence of phimosis was sought during the interview. RESULTS: Lymph node invasion was confirmed in 2 patients with PI = 6 and in 1 patient with PI = 5. Diagnostic lymphadenectomy showed no evidence of lymphatic spread in 1 patient with PI = 3 and in another patient with PI = 4. The remaining 6 patients with PI < 2 did not undergo lymphadenectomy. Phimosis was associated in 73% of the cases. CONCLUSIONS: PI is a reliable index for lymph node invasion. Patients with PI < 4 do not require therapeutic lymphadenectomy. Phimosis should be operated early in childhood.

[Splenic abscess secondary to xanthogranulomatous pyelonephritis].

OBJECTIVE: We report another case of splenic abscess after nephrectomy, a condition which must be considered in the differential diagnosis of post-operative fever. METHODS/RESULTS: A 20-year-old man presented with lumbar pain and fever. A diagnosis of xanthogranulomatous pyelonephritis was made and he was treated by subcapsular nephrectomy. Thirty days later the patient presented with a lumbar fistula from a splenic abscess and was treated by splenectomy. CONCLUSIONS: Fistulas and abscesses are more common after nephrectomy for xanthogranulomatous pyelonephritis. In our view, the subcapsular approach is an additional risk factor for the foregoing complications.

[Transitional carcinoma of the prostate. Report of a case treated with chemotherapy].

A case of transitional cell carcinoma of the prostate is described which had been diagnosed following TUR of the prostate due to cervico-prostatic obstruction. Subsequent cystoscopic and cytological controls, as well as multiple bladder biopsies have discarded a concomitant urothelial tumor. We underscore the rarity of transitional cell tumor of the prostate, its response to chemotherapy and the possibility of suspecting this tumor type when there is massive invasion of the prostate following TUR.

[Retroperitoneal abscess. Report of 2 cases].

Two cases of retroperitoneal abscess that had recently been treated in our service are described. The primary infection was localized to the psoas muscle in one patient with a previous injury to the right lumbar region. The other case was secondary to an ascending urinary infection. Staph aureus were isolated in the first case and E. Coli in the second. The different clinical course and treatment of each case are described.
