Pneumosiderosis or Welder's lung is an occupational lung disease which is usually seen after chronic exposure to iron dust. We present a case of a 64-year-old welder in whom the diagnosis of pneumosiderosis was made by lung biopsies. We also briefly review the literature regarding the disease, its prognosis and association with development of lung cancer. Avoidance of iron dust exposure and imp...
