Several common necrosis types in human tissues. a An area of liquefactive or lytic necrosis from a lung abscess, which is fraught with inflammatory cells. b An area of coagulative necrosis from a kidney infarction showing that all necrotic cells have lost their outlines and cellular morphology but the renal histology still remains intact. Note that there are few inflammatory cells infiltrating into this large necrotic area. c An area of caseation necrosis from a tuberculous lymph node showing the lack of massive infiltration of inflammatory cells. d An area of fibrinoid necrosis from a heart with rheumatic disease showing the lack of extensive infiltration of inflammatory cells
