肺组织散在肉芽肿

肺组织散在肉芽肿

肺实质中可见数个散在的肉芽肿,由此可见肉芽肿的局限性特点。这也是肺结核病或其它肉芽肿疾病胸部X线检查被描述为网织结节状的原因。活检时采样错误也有可能导致检查不到这样的病变。

The focal nature of granulomatous inflammation is demonstrated in this microscopic section of lung in which there are scattered granulomas in the parenchyma. This is why the chest radiograph with tuberculosis or other granulomatous diseases is often described as "reticulonodular". A biopsy could miss such lesions from sampling error, too.
