[Bilateral malignant mesothelioma of the tunica vaginalis testis. Apropos of a case]. / Mésothéliome malin bilatéral de la vaginale testiculaire. A propos d'un cas.

The authors report the first case of synchronous bilateral malignant mesothelioma of the tunica vaginalis. Despite bilateral radical orchidectomy completed by unilateral inguinal radiotherapy, the patient developed an uncontrolled recurrence three years after initial treatment of the second tumour. The prognosis of malignant mesothelioma is very poor with a median survival of 28 months reported in the literature.

Nephrogenic adenoma of the bladder in renal transplant recipients: a report of 9 cases with assessment of deoxyribonucleic acid ploidy and long-term followup.

PURPOSE: We evaluated the outcome of nephrogenic adenoma, a benign tumor rarely encountered in renal transplant recipients. MATERIALS AND METHODS: Between 1985 and 1993, 9 renal transplant recipients with a nephrogenic bladder adenoma removed by endoscopic resection were followed for 24 to 88 months (mean 40). Tumor deoxyribonucleic acid ploidy was assessed by flow cytometry at diagnosis and/or relapse. RESULTS: The relapse rate was 88%. The tumors were diploid and of low proliferating potential, and showed no malignant transformation. CONCLUSIONS: Our study confirms the lack of premalignant potential of nephrogenic adenomas. However, since transplant recipients might be at increased risk for bladder cancer, they should be followed closely.

[Metastasis of renal adenocarcinoma to the spermatic cord and the epididymis: 2 cases]. / Métastases d'adénocarcinome rénal au niveau du cordon spermatique et de l'épididyme: deux observations.

Metastases of renal cell carcinoma are exceptional in the spermatic cord and epididymis (17 cases reported in the literature). The authors report two cases of metastases occurring 30 and 44 months after radical nephrectomy, respectively. Both patients are alive without metastases after surgical resection, with a follow-up of 4 and 8 years after the diagnosis of renal cancer, respectively. The mechanism of development, usually retrograde venous spread, and the particular features of these metastatic sites are discussed.

[Cavernous hemangioma of the spleen: values and limitations of ultrasonic and computed tomographic diagnosis]. / Hémangiome caverneux de la rate: intérêts et limites d'un diagnostic écho-tomodensitométrique.

A case of a cavernous haemangioma associated with an hepatic haemangioma is reported. It presented in the form of a hyperechogenic mass on ultrasound imaging. On the Computed Tomography scan with contrast, the splenic tumour became progressively hyperdense: this last characteristic is observed in 6 out of 9 cases reported in the literature. MR imaging seems to allow an accurate preoperative diagnosis; nevertheless, splenectomy is often indicated because of the risk of rupture, in which case histological examination removes any doubt concerning an exceptional malignant form.

[Isolated portal vein thrombosis: a rare complication of chronic pancreatitis]. / Thrombose isolée de la veine porte: une complication rare de la pancréatite chronique.

In chronic pancreatitis (CP) portal vein thrombosis (PT) is a less well known complication than splenic vein thrombosis (ST). In the literature up until 1990, 26 cases with PT, have been reported and only 10 cases presented a isolated PT, without ST. We report a new case of isolated PT without ST in a non alcoholic man, who presented with gastroesophageal CP and a cavernomatous transformation of the portal vein. No varices ere detected by endoscopy; because the risk of bleeding was very small, a prophylactic treatment was unnecessary. The pancreas was resected preserving the spleen and cavernomatous transformation or the periportal veins and the patient was cured from his pains. The surgical tactic is an original treatment, particularly when curable pancreatic cancer is suspected.
