Figure 3. Photomicrographs of the histology of the lung biopsies (day 5 of admission) in a 43-year-old man with a history of tuberculous meningitis and rifampicin pneumonitis who presented with symptoms that mimicked severe COVID-19 pneumonia with negative test results for SARS-CoV-2 infection. (A) Histology of the lung shows thickening of the alveolar walls (Red arrow) with an increase in mononuclear cells and pink hyaline membranes (Green arrows), consistent with diffuse alveolar damage (DAD) and with acute respiratory distress syndrome (ARDS) and also with rifampicin-induced pneumonitis. Hematoxylin and eosin (H&E) ×200. (B) Histology of the lung shows some residual thickening of the alveolar walls and type II pneumocyte hyperplasia without hyaline membranes. H&E ×400.
