[Bilateral malignant mesothelioma of the tunica vaginalis testis. Apropos of a case].

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.
