Objective: To study the efficacy of percutaneous biopsy of bone or soft tissue tumors using Kerrison rongeur.

Study design: Descriptive study.

Subjects: Ten patients who had bone or soft tissue tumors, suspicious for malignancy, and underwent tissue biopsy using Kerrison rongeur at our institution.

Methods: The tumors were nipped percutaneously by sterilized Kerrison rongeur, angle 5 mm. after the skin was incised by scalpel no.11. In cases of bone tissue, a performed tunnel was achieved by a drill. Repeated nipping for 2-3 times were allowed. The tissues obtained were submitted for frozen section to evaluate their adequacy and quality. Open incisional biopsy would be proceeded if the nipped tissue was suboptimal. Complications related to the percutaneous biopsy and the final histopathology were recorded.

Main outcome measures: Tissue adequacy, tissue artifact, the histopathological interpretations, and complications related to Kerrison rongeur biopsy procedures.

Results: All patients underwent percutaneous biopsy using Kerrison rongeur, angle 5 mm. without any clinical complications. All specimens obtained by Kerrison rongeur biopsy were pathologically representable for histopathologic diagnosis without significant tissue artifact.

Conclusion: Percutaneous tissue biopsy by Kerrison rongeur was effective without any complications. The biopsied tissues were appropriate for pathologic interpretation without tissue artifact.
