Interstitial lung disease: silicosis, a case report

Abstract

A 51-year-old male had dry cough and chest pain for more than 10 years. He has a history of exposure to biomass. He worked as supervisor of tunnel construction. Twelve years ago he had hemoptysis, for which he received anti-tuberculosis therapy despite not having smear-positive. The physical examination was normal except that fine crackles were found in both bases. He had an obstructive pattern in spirometry. And, there was great interstitial involvement in the lung parenchyma in tomography studies. A biopsy was performed by video thoracoscopy, which confirmed the diagnosis of silicosis.
