Pathology[✎ edit | edit source]
The mesothelioma can be macroscopically:
- diffuse mesothelioma;
- localized mesothelioma.
Microscopically it can be:
- epithelial mesothelioma – contents mostly epithelial (cellular) component;
- fibrous mesothelioma – contents mostly fibrous spindle cell–like component;
- mixed mesothelioma – contents both of these components.
Clinical notes[✎ edit | edit source]
Epidemiology[✎ edit | edit source]
Mesothelioma is uncommon. The incidence is 2,000-3,000 new cases every year in United States (compared with lung cancer: 222,000 new cases per year in USA). Up to 80% patients suffering from the mesothelioma were exposed to asbestos at work. Average survival time is only about one year. 
Patient history[✎ edit | edit source]
Mesothelioma can be occupational disease, because it is asbestos related disease.
- Asbestos exposure: workers in the manufacture of asbestos products, asbestos miners and millers, construction traders, power plant workers, boilermakers, shipyard workers, firefighters, even teachers and veterans. 
Mesothelioma is a late consequence of asbestos exposure. Can be found even more than 50 years after exposure!
Symptoms[✎ edit | edit source]
- Major symptoms are chest pain and shortness of breath.
- Other symptoms could be persistent cough, anemia, weight loss, fever, abdominal pain and swelling. 
Diagnostic[✎ edit | edit source]
- physical examination, lung function tests;
- CT or MRI;
- thoracoscopy and pleural biopsy;
- definitive diagnosis is based on microscopical examination of the biopsy by pathologist!
Treatment[✎ edit | edit source]
The options are surgical resection of tumor or chemotherapy or radiation, or their combination. Unfortunately the mesothelioma is diagnosed in an advanced stage, which causes only one year average survival time. The treatment depends on patient's overall health (if the mesothelioma can be found 50 years after asbestos exposure at work, you can expect advanced age of the patient...).
