Mesothelioma Pleural Fibroma

Mesothelioma Pleural Fibroma

Mesothelioma Pleural Fibroma. This tumor falls in the category of benign type. There are usually two types: benign (solitary) and malign/ant (diffuse). The biological behaviour of the mesothelioma cancer can be usually predicted by their gross appearance – those that form solitary, discrete masses are generally benign, whereas the other type, who grows diffusely, are usually malignant. Benign or solitary mesothelioma tumor is also called pleural fibroma. The exposure to asbestos plays no role on the aetiology of benign mesothelioma. Generally speaking it consists of a solitary type, circumscribed, small, firm mass, generally less than 3cm in diameter. Cut surface shows spirals of dense fibrous tissue. Microscopically, the tumour is predominantly composed of curls of collagen fibres and reticulin with interspersed fibroblasts. Rarely, mesothelial-lined clefts are seen in the tumor. Benign mesothelioma causes no symptoms and is detected as an incidental radiologic finding. Sometimes the tumour is associated with systemic syndrome of osteoarthropathy or hypoglycemia. Removal of the tumour is generally curative.

Mesothelioma Pleural Fibroma

Malignant or diffuse mesothelioma is rare. It is a highly malignant tumor associated with high deadly rate. The tumor is significant in view of its acknowledge association with occupational job’s exposure to asbestos fibers for a large number of years, sometimes more than 20 years. About 90% of malignant mesothelioma tumors are asbestos related which means that the patients were in direct or indirect contact with this mineral. Mechanism of carcinogenecity by asbestos is not quite clear but it appears that prolonged exposure of the mineral type of asbestos with people swallowing and breathing it is capable of inducing oncogenic mutation in the mesothelium.
