blind biopsy

HISTOPATHOLOGY

Definition A biopsy of tissue that is grossly (macroscopically) normal–e.g., obtained by endoscopy or for which imaging studies haven’t flagged a mass or lesion–e.g., liver biopsy.

Pros Blind biopsies may be positive–e.g., if a submucosal lesion is suspected, or negative and used to confirm tumour-free resection margins.

Cons Absence of malignancy in a blind biopsy doesn’t guarantee adjacent tissue is not involved by tumour.
