Epithelioid Mesothelioma Information

Mesothelioma is a form of cancer that is almost always caused by exposure to asbestos. In this disease, malignant cells develop in the mesothelium, a protective lining that covers most of the body’s internal organs. Its most often seen site is the pleura (outer lining of the lungs and internal chest wall), but it may also occur in the peritoneum (the lining of the abdominal cavity), the heart, the pericardium (a sac that surrounds the heart) or tunica vaginalis.

Epithelioid mesothelioma is the most common cell type, constituting approximately 50% to 70% of all malignant mesothelioma. These cells are relatively uniform in shape and have a tubular pattern with a distinct cell nucleus. The individual cells are shaped like cubes or multi-sided boxes.

Epithelioid is the most common kind; 50-70% cases reported are of this type, which also has the best possibility of survival. This type affects the covering surrounding the internal organs and internal surfaces in the body. Sarcomatoid is much more serious, and it affects the secondary tissues such as bone, muscles, cartilage, and/or fat. This cell is much rarer, occurring 7-20% of the time. Mixed/biphasic refers to both types of cancers at once, and make up the rest of the 20-35% of the occurrences.
