What is mesothelioma ?
Mesothelioma is a rare tumor arising from the lining cells of the peritoneal, pleural, and pericardia cavities or the tunica vaginalis of the testis. The tumors are pink in colour and are firm. They are scattered in the body cavity and are nodular and multiple.
Microscopically, the mesothelial cells consist of diffuse collection of cell resembling epithelial cell and a core of fibrous tissue is present. Acidophilic granular cytoplasm and a big vesicular nucleus is seen. Numerous blood vessel traverse within the tumor mass and the tumor does not invade the blood or lymph vessels.
