How are Infectious Pulmonary Diseases Identified Histologically?
Histology is crucial for diagnosing infectious pulmonary diseases, such as tuberculosis and fungal infections. Key features include:
Tuberculosis: Granulomas with central caseous necrosis and Langhans giant cells. Fungal infections: Presence of fungal hyphae or spores within granulomas or necrotic tissue. Bacterial pneumonia: Neutrophilic infiltration and consolidation of lung parenchyma. Viral infections: Cytopathic effects such as inclusion bodies and multinucleated giant cells.
