Two cases of mammary carcinoma with nearly complete coagulative necros
is following fine needle aspiration biopsy (FNAB) are described. Altho
ugh this occurrence rarely complicates a fine needle aspiration proced
ure, it seems to be a real possibility. Final diagnosis can be problem
atic and rests on the reassessment of the previous aspirate material,
on the ghost architecture outlines of the infarct tumorous lesion and
on any viable tissue left at the periphery of the lesion.
