In about 20% of mesothelioma cases, involvement includes which condition?

Asbestos exposure can cause multiple lung diseases that can overlap in the same patient. Mesothelioma primarily affects the pleura, but a notable subset of patients also develops parenchymal fibrotic changes from asbestos exposure. About one-fifth of mesothelioma cases have concurrent pulmonary fibrosis, i.e., asbestosis, coexisting with the pleural tumor. This coexistence reflects the broader spectrum of asbestos-related disease and helps explain why fibrosis can be seen alongside mesothelioma on imaging and pathology. Pleural plaques are common with asbestos exposure but are not a parenchymal fibrotic disease, and lung cancer is a separate malignancy; the question specifically points to the fibrotic process that can accompany mesothelioma in a subset of patients.
