Cytokeratin immunostain may be useful in confirming the infiltration of cytokeratin positive cells within adipose tissue skeletal muscle or lung tissue figure 9. However a better understanding of how the mesothelium responds to obesity is essential.

Epithelioid mesothelioma is the most common subtype 75 of mpm. Ultrastructural features of mesothelioma include a microvillous cell membrane junctional complexes between mesothelial cells pinocytic vesicles and a distinct basal lamina. Pattern and the focal invasion of underlying adipose tissue are in keeping with the malignant nature of this mesothelial proliferation.

6 the definitive diagnosis of mpm rests on pathologic evalu ation. Monolayer of epithelial of mesodermal origin that lines the visceral serosa. On morphology signs of malignancy include invasion for instance in the adipose tissue lung and skeletal muscle and the keratin really can be helpful to highlight the invasion of the neoplastic cells.

However as you know many times in small biopsies we will not have adipose tissue lung or. Microfilaments are often abundant within the cytoplasm.

Lipoma and liposarcoma are infrequent neoplasms of mesenteric and retroperitoneal adipose tissue. The number of rois per tissue varies due to the presence of the tissue within a scan or the ability to create an roi within the tissue. Pulmonary artery with artifact ivc pleural effusion and mesothelioma have fewer than 28 scans due to the limited presence of these tissues within the scans.

Introduction malignant mesothelioma 1. We propose a hypothesis in which adipose mesothelial cells represent a visceral depot specific determinant of adipose tissue health in obesity. Given the diverse functions of mesothelial cells the mesothelium lining visceral adipose depots may be a potential contributor to tissue dysfunction in obesity including the development of fibrosis and inflammation figure 1 key figure.

Not apparent or very small in young and older rodents respectively. Here we highlight and consolidate literature from various fields of study that points to the visceral adipose associated mesothelium as a potential contributor to adipose development and remodeling.
