Granulomas are found in Tuberculosis but I want to know whether caseous, fibrotic and non caseating granulomas indicates different disease condition or all of them are found in a single patient.
I think so. Inflammatory response to Mycobacterium tuberculosis my be responsible of different stages of this disease in a sigle patient. Moreover, different types of granulomas will dpend of the site of localization (nodes, parenchima, osous tissue, etc).
