Primary malignant deciduoid peritoneal mesothelioma: a report of the cytohistological and immunohistochemical appearances
…deciduoid mesothelioma (MDM) is a rare variant of epithelioid mesothelioma. This type of tumor might be associated with the asbestos exposure and carries a poor prognosis in general. MDM was first described by Nascimento et al…

Pluripotential nature of mesotheliomata induced by inhalation of erionite in rats
…more frequently by inhalation of erionite than by asbestos inhalation. Erionite-induced tumours have in general a similar ultrastructural appearance to inoculum-induced pleural and peritoneal mesotheliomata. Unusual features of these tumours were the presence of…
