Asbestosis is an occupational lung disease defined as pulmonary fibrosis caused by asbestos. Asbestosis was previously reported in Thailand based on radiologic findings, which demonstrated interstitial lung with calcified pleural plaques, and the patient worked in a fiber cement factory. However there was some doubt about the diagnosis because clinical and radiological findings are nonspecific; there was no data support of asbestos exposure in the patient and no histologic confirmed diagnosis. Histologic diagnosis is most useful when an equivocal of a history of asbestos exposure in patients with interstitial lung diseases take place. The authors report a patient presenting with progressive dyspnea for 2 years. She worked in an electric, wire, mesh fan cover factory to check quality of protective wire mesh for 10 years until the factory was closed 6 years ago. This type of factory had never officially reported asbestos use. Her clinical manifestations and radiologic findings are compatible with interstitial lung disease. She subsequently underwent thoracotomy with wedge lung resection. Pathology revealed interstitial fibrosis with honeycombing. Asbestos bodies were found more than 10 per cm2 in the fibrosis. She was diagnosed asbestosis. The patient is suffering from dyspnea, severe hypoxemia and cor pulmonale. The patient is put on waiting lists for heart lung transplantation. The authors thus confirmed that asbestosis exists in Thailand. A policy to protect workers and people who may have risk of asbestos exposure is necessary, since diseases related to asbestos are incurable, but preventable.
