肺结核淡黄*色肉芽肿


肺结核可见散在淡黄*色肉芽肿,主要出现在肺上部。一些较大的肉芽肿中央有干酪样坏死。肺肉芽肿疾病大致表现为大小不一的圆形结节,质地坚韧,呈淡黄*色。较大的结节可能存在中央部位的干酪样坏死--包括液化性坏死和凝固性坏死的过程)。
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).
