Explain of Pulmonary Pathology

32.Lung, tuberculosis with granulomatous inflammation, gross

Here is the gross appearance of a lung with tuberculosis. Scattered tan granulomas are present, mostly in the upper lung fields. Some of the larger granulomas have central caseation. Granulomatous disease of the lung grossly appears as irregularly sized rounded nodules that are firm and tan. Larger nodules may have central necrosis known as caseation--a process of necrosis that includes elements of both liquefactive and coagulative necrosis).
