[Malignant mesothelioma of the testicular tunica vaginalis]. / Mésothéliome malin de la vaginale testiculaire.

Malignant mesothelioma of the tunica vaginalis, a rare tumour, affects men over the age of 50 years and presents in the form of a testicular mass. It is rarely suspected preoperatively and the diagnosis is suggested by the presence of numerous nodules in the tunica vaginalis. This tumour has a high metastatic potential and raises the problem of numerous local recurrences. The diagnosis is histological with negative biological markers. Treatment is difficult; the first step must consist of surgery. The indications for radiotherapy have yet to be defined.

[Report of a case of penile metastasis. Review of the literature]. / Métastases péniennes à propos d'un cas. Revue de la littérature.

Penile metastases are rare. They occur an average of 2 years after diagnosis of the primary tumour and are frequently associated with disseminated metastases. Treatment is more often palliative than curative, allowing a survival of 2 years. The authors report a case of penile metastasis secondary to a rectal cancer, discovered 29 months after treatment of the primary site. Survival with chemotherapy was 15 months.

[A case of association of cyst of the urachus and Meckel's diverticulum]. / Un cas d'association entre kyste de l'ouraque et diverticule de Meckel.

Meckel diverticulum and residual urachus have a common embryological origin: the yolk sac at the eight day of life. Their course is independent but the underlying mechanisms are identical. Meckel diverticulum occurs in 2 to 4% of the population. Clinical signs are often absent and complications occur in 4% of the cases (haemorrhage, occlusion, inflammation, and rarely tumoural formation). Residual urachus occurs as a cystic formation, a sinus or a fistulization and may degenerate into adenocarcinoma of severe prognosis. The reported association has not apparently been reported previously in the literature. Due to the risk of cancerization, it is suggested that residual urachus should be searched in cases of Meckel diverticulum.
