pleural inflammation
Although certain inflammatory disorders yield characteristic morphological changes in pleural biopsies, the histological appearance of pleural inflammation is often diagnostically nonspecific.
The generic response to pleural injury is characterized by neutrophils and chronic lymphocytic inflammation, fibrin deposition, fibroplasia, and reactive angiogenesis.
