title: Tumors of the foot and ankle: a single-institution experience.
abstract: Tumors of the foot and ankle are rare, and the particular clinicopathologic features, therapeutic approach, and outcomes in this setting are not well established. From January 2000 to December 2010, 72 patients with primary musculoskeletal tumors of the foot and ankle, both benign and malignant, were treated at a single institution. Of the 72 patients, 56% were female. The median age was 52 years. Of the 72 tumors, 62 (86.11%) were located in the foot and 10 were located in the ankle; 63 (87.5%) were soft tissue tumors and 9 (12.5%) were bone tumors. Overall, 56 (78%) were benign tumors and 16 (22%) were malignant tumors. The most frequent soft tissue and bone diagnosis was giant cell tumor. The median follow-up period was 49 months. The vast majority of the tumors were located in the foot. Benign tumors were dominant, outnumbering malignant tumors by more than 3 to 1. The diversity of the histologic benign types was evident, with giant cell tumor, angiomyoma, and lipoma the most frequent. Regarding the malignant tumors, a clear male predominance was present, the median age was 45 years, and the most frequent tumor was synoviosarcoma. The 9-year overall and disease-free survival rate was 65% and 40%, respectively.
