Soft-tissue biopsy technique.

Soft-tissue Biopsy Technique

The instrument described here consists of a special syringe on which sharp cutting needles of various sizes are mounted. These produce undistorted biopsy specimens. Suction is used only to retain the specimen within the needle, and the cleancut cylinder of tissue is quite unlike that obtained by aspiration. Gillman and Gillman&2 used this principle for their liver biopsy instrument. We have ret...

Oral soft-tissue biopsy: an overview.

Proper management of an oral mucosal lesion begins with diagnosis, and the gold standard for diagnosing disease, oral or otherwise, is tissue biopsy. The oral environment, which is moist and confined, poses challenges for collecting a viable tissue sample that will be suitable for diagnosis. These challenges are further compounded by the myriad of biopsy techniques and devices now available. In...

Ultrasound guided core needle biopsy of soft tissue tumors; a fool proof technique?

AIM To assess technical and lesion related factors affecting the quality of ultrasound guided core needle biopsy (CNB) of musculoskeletal soft tissue tumors. MATERIALS AND METHODS Data of 223 CNBs were evaluated in a retrospective study. Diagnostic yield was calculated for all lesions on the basis of lesion location (extremity/torso), examiner, biopsy needle gauge/length and number of acquire...

Vacuum-assisted minimally invasive biopsy of soft-tissue tumors.

BACKGROUND Although exact histological characterization of soft-tissue tumors is essential for determining the appropriate therapy, the quality of the histological assessment is often limited by the size of the tissue samples. Incisional biopsy and core needle biopsy have been the most effective techniques for obtaining tissue samples from soft-tissue tumors. This study was performed to investi...
