Incisional Biopsy Versus Core-needle Biopsy in Bone Tumors Analysis

Evaluation of Agreement in Histological Findings Between Core Needle and Incisional Biopsies

The investigators will collect data of patients with high suspicion of malignant bone tumor based on radiological imaging who underwent/will undergo both core needle biopsy and incisional biopsy for diagnostic confirmation by histological examination.
