[The morphological characteristics of the lung lesions in straighteners working with brass-bronze alloys].

Morphologic study of lung specimens obtained during diagnostic thoractomy in 6 workers engaged in smelting brass-bronze alloys showed changes typical of exogenous fibrosing alveolitis, namely, terminal bronchiolitis with pseudopolypous growth in the submucous layer, vasculitis (predominantly arteritis) paralleled by secondary recalibration of vessels, arteriolar and venular shunting, and microcirculatory disorders.
