[Pleuro-pulmonary metastases from a malignant mesothelioma of the tunica vaginalis]

Abstract

Introduction: Mesothelioma is a malignant tumour of the serous membranes that principally affects the pleura. Peritoneal, pericardial and tunica vaginalis mesothelioma are very rare.

Case report: We report the case of a 65-year-old male with malignant mesothelioma of the tunica vaginalis (MTV). He presented with several local recurrences and, five years after the initial surgery, with pulmonary nodules and a pleural effusion. Pleural biopsies confirmed epithelioid mesothelioma. A diagnosis of pleuro-pulmonary metastases from previous malignant MTV was made.

Conclusions: Malignant MTV is a rare and aggressive tumor with frequent local recurrences and, rarely, visceral metastases. This case report emphasizes the difficulties of the differential diagnosis between pleural mesothelioma and pleural metastases from MTV. The lack of any treatment for metastatic malignant MTV is discussed.
