The very rare benign chondroblastoma occasionally invades soft tissues and may grow beyond the epiphysis into the metaphysis. In the present case such a tumour did not show the typical radiological appearances, but presented malignant features both on plain films and on the angiogram. The importance of biopsy of tumours which cannot be identified with certainty must be stressed before radical surgery is carried out.
极为罕见的良性软骨母细胞瘤偶尔会侵犯软组织，并且可能超越骨骺生长至干骺端。在本病例中，这样的肿瘤并未表现出典型的放射学表现，而是在平片和血管造影片上均呈现出恶性特征。在进行根治性手术之前，必须强调对无法明确诊断的肿瘤进行活检的重要性。
