biopsy tract
Path of tissue contamination created during needle or incisional biopsy that must be excised during definitive surgery.
Full Definition
The biopsy tract refers to the pathway of potential tumor contamination created during diagnostic tissue sampling, including the needle path in core biopsies or the incision site in open biopsies. In orthopedic oncology, the entire biopsy tract must be completely excised during definitive surgical resection to prevent local recurrence from residual tumor cells. Poor biopsy technique, such as transverse incisions or violation of multiple compartments, can significantly compromise subsequent limb-salvage procedures and may necessitate amputation. Proper biopsy planning considers the definitive surgical approach to ensure the tract can be safely excised.
Usage
Usage note: Always document complete excision of biopsy tract in oncological procedures.
