Diagnostic criteria for human diffuse malignant mesothelioma

Abstract

Diffuse malignant mesothelioma is a rare tumor in the general population, yet is unique in that it is caused almost exclusively by exposure to asbestos with long-term latency (15 years and over). Pathologists are required to provide a reliable diagnosis of the tumor for clinicians who are responsible for the treatment of affected patients. Pathological diagnosis of diffuse malignant mesothelioma is not always easy; however, it has improved over the last few decades. Currently, comprehensive analysis, including gross appearance, histology, histochemistry, immunocytochemistry and electron microscopy is recommended as the best approach to an accurate diagnosis of diffuse malignant mesothelioma.
