Hepatic mesothelioma.

We report a 70-year-old woman with mesothelioma in the liver. The tumor was excised, and the patient is well two years later. Light microscopy of the tumor showed papillary and tubular pattern, in addition to areas of densely packed cells arranged in fascicles. These features and the results of histochemistry and immunohistochemistry indicate a probable histogenesis from submesothelial connective tissue.
