How is granulomatous lung disease distinguished from caseation?
Although noncaseating or nonnecrotising granulomas are the hallmark of sarcoidosis, discrete areas of fibrinoid necrosis may be seen in the centre of some granulomas in cases of typical sarcoidosis. This type of necrosis is distinguishable from caseation by the persistence of an intact reticulin pattern, as shown by silver staining.
