biopsy

 [bi´op-se]
removal and examination, usually microscopic, of tissue from the living body, often to determine whether a tumor is malignant or benign; biopsies are also done for diagnosis of disease processes such as infections.
Technique for endometrial biopsy. Longitudinal strips of the endometrium are sampled using an in-and-out and rotational motion. From Rakel, 2000.
aspiration biopsy one in which tissue is obtained by application of suction through a needle attached to a syringe.
brush biopsy one in which the sample is obtained by a brush with stiff bristles introduced through an endoscope, such as for a tissue sample from an inaccessible place such as the renal pelvis or bronchus.
chorionic villus biopsy chorionic villus sampling.
cone biopsy one in which an inverted cone of tissue is excised, as from the uterine cervix.
endoscopic biopsy removal of tissue by instruments inserted through an endoscope.
excisional biopsy removal of biopsy tissue by surgical cutting, such as a lumpectomy.
fine-needle aspiration biopsy aspiration biopsy using a fine needle. For superficial tissue such as the thyroid, breast, or prostate the needle is unguided, but for deep tissue it must be guided radiologically.
incisional biopsy biopsy of a selected portion of a lesion.
needle biopsy (percutaneous biopsy) one in which tissue is obtained by insertion through the skin of a special type of needle (see biopsy needle).
punch biopsy one in which tissue is obtained by a punch-type instrument.
sentinel node biopsy biopsy of a sentinel node (the first lymph node to receive lymphatic drainage from a malignant tumor). It is identified as follows: a dye and a radioactive substance are injected into the body, which causes certain nodes to “light up” like a sentinel, indicating that they are the most appropriate ones for examination. They are detected by both the light created by the dye and the radioactive substance that is monitored by a gamma camera. If the sentinel nodes do not contain malignant cells, this usually eliminates the need for removal of more distal nodes. Called also intraoperative lymphatic mapping.
shave biopsy biopsy of a skin lesion by excising it with a cut parallel to the surface of the surrounding skin.
stereotactic biopsy biopsy of the brain using a stereotactic technique to locate the biopsy site. This can be done as a minimally invasive surgery technique. The patient's head is held in a special rigid frame so that a probe can be directed into the brain through a small hole in the skull.
sternal biopsy biopsy of bone marrow of the sternum removed by puncture or trephining; see also sternal puncture.

nee·dle bi·op·sy

any method in which the specimen for biopsy is removed by aspirating it through an appropriate needle or trocar that pierces the skin, or the external surface of an organ, and into the underlying tissue to be examined.
Synonym(s): aspiration biopsy

needle biopsy

the removal of a segment of living tissue for microscopic examination by inserting a hollow needle through the skin or the external surface of an organ or tumor and rotating it within the underlying cellular layers. Also called fine-needle aspiration. See also aspiration biopsy.

needle biopsy

Fine-needle aspiration A diagnostic preparation similar to aspiration cytology, but uses a larger bore–eg, 19-gauge, needle to obtain architecturally intact tissue, yielding a higher diagnostic success rate than with cytology alone. Cf Needle aspiration cytology.

biopsy

removal and examination, usually microscopic, of tissue from the living body. Biopsies are usually done to determine whether a tumor is malignant or benign; however, a biopsy may be a useful diagnostic aid in other disease processes such as infections.

aspiration biopsy

bite biopsy
instrumental removal of a fragment of tissue.
bone marrow biopsy
obtaining a sample of bone marrow, usually by needle aspiration, from a long bone, rib or sternum, for cytological examination.

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.

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.

see needle biopsy (below).
hepatic biopsy
may be by transperitoneal incision, more commonly by percutaneous needle or trocar and cannula technique.
incisional biopsy

biopsy in which tissue is obtained by puncture of a tumor, the tissue within the lumen of the needle being detached by rotation, and the needle withdrawn.
punch biopsy
see punch biopsy.
