| If present, they represent entrapped benign mesothelium or epithelium. |
| It does help to distinguish mesotheliomas from reactive, proliferating mesothelium, which typically has no cytogenetic abnormalities. |
| Albumin is considered a good marker of capillary permeability in the pleura, because there is no evidence that albumin is produced or stored in pleural mesothelium. |
| But very early this tissue is increased to form a massive layer by direct development from the mesothelium. |
| Mesothelioma is a disease in which cells of the mesothelium become abnormal and divide without control or order. |
| However, a mesothelial origin of this tumor has been questioned, since these tumors are seen in sites where mesothelium is not found. |
