Mesothelioma Lung Gross
Some patients get a small bowel obstruction when the tumor extends through the diaphragm a muscle.
Mesothelioma lung gross. Less commonly the lining of the abdomen and rarely the sac surrounding the heart or the sac surrounding the testis may be affected. Peritoneal mesothelioma which occurs in tissue in the abdomen causes signs and symptoms that may include. Following the initial diagnosis of mesothelioma it is important to confirm the location of the tumor and its gross findings before histological examination. Pleural mesothelioma which affects the tissue that surrounds the lungs causes signs and symptoms that may include.
The most common area affected is the lining of the lungs and chest wall. The epithelioid component in biphasic malignant mesothelioma bmm may exhibit intra alveolar growth mimicking desquamative pneumonitis. Mesothelioma is a type of cancer that develops from the thin layer of tissue that covers many of the internal organs known as the mesothelium. It usually occurs from prior exposure to asbestos a type of mineral fiber used in the insulation industry.
Malignant mesothelioma may appear as an intraparenchymatous lung tumour due to the infolding of the mesothelium. Most patients with mesothelioma of the lung die as a result of respiratory failure or pneumonia. In the case of a pleural mesothelioma a tumor in the lung parenchyma suggests lung cancer with a pleural extension.
