Sarcomatoid mesothelioma is a rare malignant cell type and only accounts for between 10-15% of all mesothelioma cancer cells. This is least common type of mesothelioma. Sarcomatoid mesothelioma cells are oval shaped, but consistently irregular and not as uniform as epithelioid mesothelioma cells. The nucleus of sarcomatoid cells, so clear and distinguishable in epithelioid cells of the same type, is muddled and not as visible.
The oval shape of the sarcomatoid mesothelioma cells is common in other cell structures, and while it is not often associated with mesothelioma, they can closely mimic those of other malignancies, including those of sarcomatoid carcinoma and sarcoma. While sarcomatoid mesothelioma cells can manifest in other parts of the body, there are relatively rare within the lungs (the origin of most mesothelioma malignancies).
Pulmonary sarcomatoid carcinoma is that carcinoma most closely mimics sarcomatoid mesothelioma. Symptoms of both cell type also parallel, including chest pains, effusions of the chest and abdomen, and difficulty breathing.
Mesothelioma is a rare but aggressive malignancy typically associated with poor prognosis. Mesothelioma is associated with exposure to asbestos, a fibrous mineral used in a number of different industrial materials and products. Records now indicate that most asbestos manufacturers knew of the hazards asbestos posed and yet still continued to use it in their products, exposing hundreds of thousands of those who worked the material on a daily basis. If you or a loved one has been exposed to asbestos and you believe you may have an asbestos related injury or health disorder, please fill out the brief form on this page and we’ll be pleased to send you a complimentary asbestos exposure and mesothelioma information packet. Inside you’ll find information about top doctors and treatments for asbestos related injuries as well as information on you may be able to obtain financial compensation for your injuries.
