What is the histology of granuloma?
Histologically, the granulomas are necrotizing and non-necrotizing, predominantly necrotizing with large necrotic center that is surrounded in the periphery by epithelioid histiocytes, lymphocytes, and multinucleated giant cells. These granulomas microscopically are similar to histoplasma.
