肉芽肿干酪样坏死。图示广泛肉芽肿病变。原发于肺尖部的多个干酪样肉芽肿是继发性肺结核的最典型特征。然而真菌性肉芽肿（组织胞浆菌病，隐球菌病，球孢子菌病）也具有这样的外观。
On closer inspection, the granulomas have areas of caseous necrosis. This is very extensive granulomatous disease. This pattern of multiple caseating granulomas primarily in the upper lobes is most characteristic of secondary (reactivation) tuberculosis. However, fungal granulomas (histoplasmosis, cryptococcosis, coccidioidomycosis) can mimic this pattern as well.
