Abstract
A case of malignant pleural mesothelioma due to asbestos in a 61-year old male was presented. Pathologically, the right lung was enshrouded with a thick layer of tumor tissure, which invaded the chest wall, diaphragm and liver. The tumor tissue was mixed epithelial and mesodermal form in histologic structure. No distant metastasis, including hilar lymph nodes, was found.
Bilateral calcified diaphragmatic pleural plaque on chest roentgenogram, and his occupational history of working in a dockyard for 27 years, indicated asbestos dust exposure.
In mineralogical examination, although both amosites and chrysotiles were found in lung tissue, only chrysotiles were found in tumor tissue. The meaning of this is unclear, but possibly, chrysotiles might have played a more important role in the occurrence of mesothelioma in this case.
