图示：粟粒性结核病
免疫反应较差时，病变可呈粟粒样播散，如图可见肺组织中大量散在的直径1-2mm的粟粒样肉芽肿。
With a poor immune response to the agents producing granulomatous inflammation, there is extensive spread of infection with the production of a "miliary" pattern of granulomas as seen here in the lung of a patient with miliary tuberculosis. The 1 to 2 mm granulomas are scattered around like millet seeds.
