  Silicosis is considered to be among the occupational lung diseases and associated with sandblasting, mining, quarrying and tunneling. Acute silicosis is usually progressive diseaseand despite treatment with corticosteroids it leads to cardio-respiratory failure and death. Alveolar silicoproteinosis is one of it’s acute presentations due to exposure to silica dust and lungs filling with proteinaceous material. Here, we have presented a 29 year old male sandblaster with the three conditions of acute silicosis, secondary alveolar proteinosis and pulmonary tuberculosis on four anti tuberculous medications who presented with respiratory distress.
