Abstract: | Abstract We report the case of a 75-year-old Japanese man who developed malignant mesothelioma in the left hemithorax 50 years after the dropping of the atomic bomb on Nagasaki in 1945. This may be the first reported case of malignant mesothelioma following exposure to atomic radiation. Asbestos is the leading cause of malignant mesothelioma, but radiation therapy is the primary non-asbestos-related cause. In the case of radiation therapy, the interval between exposure and the occurrence of malignant mesothelioma tends to be many years. This patient was at a high risk of malignant mesothelioma as he had been exposed to radiation from the atomic bomb and may also have had a history of asbestos exposure at the munitions factory where he was employed as a shipbuilder for 2 years. It has been suggested that combined exposure to atomic radiation and asbestos is associated with an increased incidence of malignant mesothelioma. If thickening of the pleura or pleural effusion is found in atomic bomb survivors, malignant mesothelioma should be considered as one of the options in the differential diagnosis, even although the atomic bomb attacks occurred several decades ago. |
