BCG granuloma: well defined multiple granulomas, variable caseating necrosis and Langhans giant cells Since AFB stain identifies acid-fast bacilli in only 1/3 of cases, it is rarely used in a patient with a history of BCG treatment (see Figure 2) Foreign body granuloma composed of foreign material and granulomatous inflammation (see Figure 3) Print. Core needle biopsy is a sensitive method for diagnosing necrotizing granuloma of the lung, but FNA biopsy is insufficient for diagnosis. Therefore, the main difference between caseating and noncaseating granuloma is that the noncaseating granulomas do not have a necrotic center while caseating granulomas do.

Macrophages acquire a large amount of cytoplasm in this process and consequently start resembling epithelial cells. There were 21 females and 14 patients were African Americans. Granulomas are complex multicellular tissue reactions formed after a cascade of interactive systems that encompass adhesion molecule activity, capillary permeability, and chemokine, cytokine action. However, misconceptions do exist, including the concept that finding AFB in "caseating granulomas" confirms the diagnosis of tuberculosis. The lung foci account for the majority of clinical cases of tuberculosis. If tissue biopsy reveals noncaseating granulomas, and other similarly-presenting diseases (tuberculosis, fungal disease, lymphoma, lung cancer) can be ruled out, sarcoidosis is the likely diagnosis.
