Histoplasma can act like TB and cause cavitary lesions and calcified nodules with fibrotic scarring. In general, fungi are combatted by lymphocytes and macrophages, not eosinophils or neutrophils.

Can anyone explain why bacteria is neutrophils, viral/fungi are lymphocytes? I know this is a fundamental concept...

lolmedlol  i think neutrophils (in addition to lacking granzymes and perforins which are used to kill viruses and fungi) dont recognize intracellular things; viral antigens needs to be processed and presented on an MHC for the lymphocytes to recognize +1  
usmile1  also neutrophils are only seen in acute inflammation. This pt has longstanding inflammation which is associated with monocytes, lymphocytes, macrophages, plasma cells. +
