Explain of Pulmonary Pathology

43.Lung, miliary tuberculosis, gross

When the immune response is poor or is overwhelmed by an extensive infection, then it is possible to see the gross pattern of granulomatous disease seen here. This is a "miliary" pattern of granulomas because there are a multitude of small tan granulomas, about 2 to 4 mm in size, scattered throughout the lung parenchyma. The miliary pattern gets its name from the resemblence of the granulomas to millet seeds.
