title: Asymptomatic localized pleural amyloidosis mimicking malignant pleural mesothelioma: report of a case.
abstract: We herein report an asymptomatic 65-year-old male with localized pleural amyloidosis mimicking malignant pleural mesothelioma. He had a history of exposure to asbestos and was admitted for investigation of an abnormal pleural thickness detected by chest radiography. Positron emission tomography showed elevation of standardized uptake value corresponding to the pleural thickness. Partial pleurectomy including the tumor was performed for the purpose of diagnosis and local disease control. The pathological examination showed that the tumor was pleural amyloidosis. The tumor was diagnosed as localized primary amyloidosis, because serum monoclonal protein concentration did not increase. Pleural amyloidosis should be considered as a differential diagnosis from pleural mesothelioma.
