Overview
Biopsy of Ewing sarcoma is important for confirming the diagnosis and determining histologic subtype.[1] Biopsy may be performed percutaneously with either a fine-needle, or wide-bore needle, or through a formal incision.
Biopsy
- Biopsy of Ewing sarcoma is important for confirming the diagnosis and the determining histologic subtype.[1]
- Biopsy may be performed percutaneously with either a fine-needle, or a wide-bore needle, or through a formal incision.
- More invasive methods carry a higher risk of complications and contamination of tissue planes. Each year 30% of patients loose their limbs through inappropriate biopsy site and technique. In principle, biopsies should be performed at a tumor center by a specialist in tumor surgery.
- Inappropriate alignment of the biopsy or inadvertent contamination of soft tissues can render subsequent limb-preserving reconstructive surgery impossible.
