The authors reviewed 260 cases of bone tumors localized in the foot and treated at the Tumor Center of the Rizzoli Orthopaedic Institute: 191 were benign and 58 malignant and 11 metastasis. There was predilection for the hindfoot (57%), followed by the forefoot (33%) (prevalently the metatarsals). Localizations in the midfoot were rare (10%). Osteoid osteoma was observed in 26% of all of the tumors of the foot and in 35% of the benign forms. Among malignant neoplasms Ewing's sarcoma (27.5%) was the most frequent. Conservative surgery, which was always carried out in benign tumors, was also performed in some of the malignant ones, having an early diagnosis and a correct preoperative study. The indications and the limits of the different imaging techniques available are reported (bone scan, arteriography, CAT, MRI), and the role of biopsy in the definitive diagnosis of these neoplasms in discussed.
作者回顾了里佐利骨科研究所肿瘤中心收治的260例足部局限性骨肿瘤病例：191例为良性，58例为恶性，11例为转移瘤。好发于后足（57%），其次是前足（33%）（主要是跖骨）。中足部位发病较少（10%）。骨样骨瘤在所有足部肿瘤中占26%，在良性肿瘤中占35%。在恶性肿瘤中，尤因肉瘤最为常见（27.5%）。对于良性肿瘤，始终采用保守手术治疗，部分早期诊断且术前检查正确的恶性肿瘤也采用了保守手术。报告了现有不同成像技术（骨扫描、动脉造影、计算机断层扫描、磁共振成像）的适应证和局限性，并讨论了活检在这些肿瘤明确诊断中的作用。
