[Pleural and mediastinal metastases from a malignant mesothelioma of testicular vaginalis membrane].

The authors describe an original observation of secondary intrathoracic metastases due to a malignant adenomatoid tumour or mesothelioma of the testicular tunica vaginalis. The hypothesis of a primary pleural mesothelioma could be excluded here as could secondary pleural deposits from another neoplasm. The exceptionally malign potentialities of this common tumour of the testicular adnexae were reviewed as well as the extremely poor prognosis.
