Bone tumors of the foot: epidemiology and diagnosis.
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.
