Understanding Sarcomatoid mesothelioma

Sarcomatoid mesothelioma is a rare cell type of cancer caused by asbestos exposure.

It has both sarcomatous (connective tissue) and epithelial (lining) elements. The cells have an oval or spindle shape. It can occur in several organs, including the uterus, kidneys, lungs, and the lining of the belly (peritoneum). It makes up 10 to 20 percent of mesothelioma diagnoses.
