[Erionite, an exposure factor linked to pleural mesothelioma].

Abstract

Mesotheliomas are neoplasia developed from the mesothelium, a layer covering the viscera (visceral layer) and the cavity where the organs are (parietal layer). The best known, and the most frequently encountered is the pleural mesothelioma. This disease has a close link with exposure to asbestos, a mineral fibre now banned in several countries. However, other exposure factors have also been incriminated, including another one recognised as a certain carcinogenic agent for several years now : erionite. We present the case of a patient with pleural mesothelioma whose exposure to erionite could be demonstrated. The presentation of this clinical case will be complemented by a literature review on this less known and mostly environmental exposure, contrary to asbestos which is mostly professional.
