[Multiple bladder inverted papillomas].

OBJECTIVE: To describe the clinical and histological findings of the unusual involvement of the urinary bladder by multiple inverted papillomas of transitional cells. METHODS/RESULTS: A 53-year-old male presented with obstructive symptoms and gross hematuria lasting for one year. Ultrasound examination of the urinary bladder demonstrated two polypoid masses. Transurethral resection was performed and histopathological examination of specimens showed a subepithelial, non-atypical cell proliferation arranged in a trabecular pattern. DNA-ploidy showed diploid population and ki-67 determination revealed a low proliferation index. CONCLUSIONS: Multiple inverted papillomas of the urinary bladder are very rare. Histological examination is essential for the definitive diagnosis. Determination of DNA-ploidy and proliferative index may be useful for appropriate management of this disease.

[Spontaneous retroperitoneal hematoma secondary to the rupture of suprarenal myelolipoma].

OBJECTIVE: To describe a case of adrenal myelolipoma in a patient that presented with retroperitoneal hemorrhage. METHODS/RESULTS: A 53-year-old patient that presented with retroperitoneal hemorrhage is described. A CT scan showed a 14 cm fat-containing mass in the right adrenal area surrounded by another hyperdense mass suggestive of hemorrhage. A right adrenalectomy was performed. Histopathologic analysis of the mass confirmed the clinical diagnosis of ruptured adrenal myelolipoma. The clinical and therapeutic aspects are discussed and the literature is briefly reviewed. CONCLUSIONS: Adrenal myelolipomas are rare benign lesions and are usually asymptomatic. Spontaneous rupture is very uncommon and is related with the size of the tumor. To our knowledge, only six cases have been previously reported in the literature.

[Treatment of erectile dysfunction with vacuum devices].

OBJECTIVE: To analyze the results achieved with vacuum devices in the treatment of erectile dysfunction. METHODS: A telephone survey was conducted on 150 patients undergoing treatment with a vacuum device. Of these, 89 responded; 79 of which were considered valid for the study. The duration and frequency of use, side effects and degree of patient and partner satisfaction were analyzed. Mean follow-up was 59.5 months. RESULTS: There were 14 dropouts early in the course of treatment. The remaining 65 patients used the device for a mean duration of 34.6 months, 3.7 times monthly. 63.3% of the patients achieved erection in more than half of the attempts. The most frequent side effects were pain (27 patients) and ecchymosis (7 patients). Forty-eight patients discontinued treatment at 10.8 months' mean follow-up. The most common causes for discontinuing treatment were lack of efficacy, refusal of the partner and pain. CONCLUSIONS: Treatment of erectile dysfunction with the vacuum constriction device should be utilized as an alternative to intracavernosal drug-induced erection therapy when oral therapy fails or is contraindicated. A male with a stable partner and impotence arising from venous leakage or mild cavernous artery insufficiency is the ideal candidate.

[Spontaneous retroperitoneal hematoma: our experience].

We report 15 cases of spontaneous retroperitoneal haematoma. The etiology and the diagnostic and therapeutic procedures were evaluated. The haematoma source was the adrenal gland in 4 patients and the causes were pheochromocytoma (1), adenoma (1), myelolipoma (1) and idiopathic (1). In 10 patients the source was the kidney and the causes were angiomyolipoma rupture (6), renal cell carcinoma (3) and ureteral calculi (1). In the remaining case, the haematoma was produced by fibrinolytic and anticoagulant therapy in a patient with acute myocardial infarction. The imaging diagnostic techniques employed were abdominal ultrasonography and CT scan, which allowed the diagnosis of haematoma and showed his size and extension in all the cases. With these two techniques, and with the retrograde pyelography in one patient, we obtained the etiologic diagnosis in 12 of the 15 cases. Surgical treatment was performed in 12 patients (adrenalectomy in 2, simple nephrectomy in 3, radical nephrectomy in 5 and partial nephrectomy in 2).

[Bladder leiomyoma during pregnancy].

OBJECTIVE: To describe an additional case of rapidly growing leiomyoma of the bladder in a pregnant woman. METHODS: A case of leiomyoma of the bladder in a woman at 8 months of pregnancy is presented. Transurethral resection was performed, but the tumor recurred a few weeks later. The tumor was resected by partial cystectomy after delivery. CONCLUSIONS: Leiomyoma of the bladder is an uncommon benign lesion that is successfully managed by surgical resection. The rapid recurrence of the tumor in our patient can be ascribed to the hormonal changes during pregnancy.

[Bladder sarcomatoid carcinoma. Bladder carcinoma simulating lymphoma].

OBJECTIVE: To describe an unusual type of vesical carcinoma (sarcomatoid carcinoma) associated with the spread of inflammation. The article discusses the diagnostic difficulties and prognosis. METHOD/RESULTS: We describe a patient with vesical sarcomatoid carcinoma associated with the spread of inflammation that practically obscured the undifferentiated area, mimicking a lymphoma. This is interpreted as a favourable immunological reaction, despite the highly aggressive behaviour of the sarcomatoid component. CONCLUSIONS: Only on rare occasions do vesical carcinomas present such a prominent degree of spindle-shaped cells. This finding could create some diagnostic confusion, hence an immunohistochemical study is essential. The identification of sarcomatoid carcinoma has important implications both for treatment and for prognosis. The literature refers to the marked aggressiveness of this type of tumour. The peculiarity of the case resides in the associated spread of inflammation which improved the prognosis.
