MSH: Neoplasms composed of tissue of the mesothelium, the layer of flat cells, derived from the mesoderm, which lines the body cavity of the embryo. In the adult it forms the simple squamous epithelium which covers all true serous membranes (peritoneum, pericardium, pleura). The concept does not refer to neoplasms located in these organs. (From Dorland, 27th ed),NCI: A benign or malignant neoplasm arising from mesothelial cells. Mesothelial cells are the lining cells of the pleura and peritoneum. -- 2003
