SARCOMATOID MESOTHELIOMA
Sarcomatoid mesothelioma is the most serious form of the disease, as it rarely responds to any treatment whatsoever. Fortunately it is also the rarest, as it only strikes 10-20% of patients with mesothelioma. It appears as spindle-shaped pattern of cells that overlap one another, and generally arises from support tissues such as bone, cartilage, muscle, and fat. Death usually occurs within six months of diagnosis of sarcomatoid mesothelioma.
