Q

TBC pulmonara micro

A

granulom tbc - 4 componente-
1. strat de necroza de cazeificare= pulbere omogena eozinofila ce contine fibre de reticulina , fibre elastice si resturi necrotice
2.macrofage epiteloide cu citoplasma diferentiata
3.celula giganta langhans= macrofage de dimensiuni mari, multinucleate, cu nucleii dispusi in palisada la periferie
4.limfocite T
