aspiration biopsy
biopsy in which tissue is obtained by application of suction through a needle attached to a syringe.
bite biopsy
instrumental removal of a fragment of tissue.

brush biopsy
removal of cells and tissue fragments using a brush with stiff bristles (introduced through an endoscope). Effective in obtaining tissue samples from inaccessible places such as the renal pelvis.
closed biopsy
one carried out without access through an open incision such as a laparotomy. An example is a percutaneous, fine needle aspirate.
cone biopsy
biopsy in which an inverted cone of tissue is excised, as from the uterine cervix.
cytological biopsy
obtaining specimens of cells by various methods including irrigation of a hollow tube.
biopsy dart
an alternative to immobilization of large and wild animals; a dart which cuts a skin bipsy, then falls out. Limited to use for superficial lesions.
endoscopic biopsy
removal of tissue by appropriate instruments through an endoscope.
excisional biopsy
biopsy of tissue removed from the body by surgical cutting.
exploratory biopsy
a combination of exploratory surgery to determine size and location of a lesion and the taking of a biopsy.

sample of cells scraped from the surface of a lesion or obtained by impression smears.
surgical biopsy

synovial biopsy
by a needle biopsy technique or through an arthrotomy incision using special forceps for a bite biopsy.
