Abstract

We report a rare case of silicosis, histologically corresponding to silicoproteinosis and tuberculosis, in a man working consecutively as a miner, blacksmith and founder. A microscopic study revealed deposits in alveoli, in which immunohistochemistry did not reveal surfactant (SP-A), that was present in the alveolar fluid in alveolar lipoproteinosis.
