Clinical aspects of coal workers' pneumoconiosis (CWP) and silicosis, including pathogenesis and pathology, were discussed. Approaches for the evaluation and management of these disorders were offered. Evidence of respiratory difficulties occurring in miners was noted as early as the 1800's. Studies of large populations of coal miners in Britain and the United States have provided much of the current knowledge about the problem. The histopathologic hallmark of CWP was the coal macule. There were no pathognomonic signs or symptoms that identify workers with CWP. Diagnosis relied on appropriate dust exposure settings and durations and the characteristic chest radiograph to distinguish between a worker with simple or complicated CWP. In simple CWP, the pulmonary function may be minimally impaired, if at all. Silicosis referred to a group of fibrotic lung diseases which result from the occupational exposure to silica (14808607). Diagnosis distinguished between classic, complicated, accelerated, and acute silicosis. Silicosis has been associated with several other illnesses including fungal or tubercular infections, connective tissue diseases, and possibly pulmonary malignancy. Proper management of patients with CWP and silicosis was briefly discussed.
