Pathological examination of soft tissue biopsy needle

1. Core biopsy: Use a cored needle biopsy to obtain cells. If the first biopsy fails to get a clear diagnosis due to the small amount of specimens, you can consider using imaging aids for re-puncture, such as CT, to confirm the diagnosis.

2. Hollow-core needle biopsy: With the assistance of imaging and CT, tumor specimens are collected through the hollow needle to obtain a clear diagnosis. Current guidelines do not recommend this approach.

3. Intraoperative frozen biopsy: Frozen biopsy of skin lesions during surgery to confirm the diagnosis. Current guidelines do not recommend this approach.

4. Open biopsy: More test specimens are helpful for diagnosis. However, there may be shortcomings such as the expansion of the scope of tumor contamination, and the requirement for re-operation is higher than that of needle biopsy. In addition, the cost of a needle biopsy is higher than that of a cored needle.

5. Resection biopsy: If the lesion is small and located in the superficial layer, the operation can be completely removed and there is no serious dysfunction. Consider resection of the lesion and tissue biopsy of the tissue lesion to confirm the diagnosis.
