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.
