Hairy pleural plaque

Last revised by Yahya Baba on 19 Dec 2020

Hairy pleural plaques are a manifestation of asbestos-related disease. They arise from the visceral pleura, typically from an interlobar fissure. The hairiness stems from short radially-oriented linear regions of fibrosis extending from the plaque into the adjacent lung parenchyma.

Compared to the usual parietal pleura-arising plaques, these hairy plaques are rare.
