title: High-grade intramedullary osteosarcoma of the talus: case report.
abstract: This is a presentation of a rare malignant tumor that uncommonly affects the bones of the foot. The following case involves a malignancy which usually presents during childhood or adolescence presenting much later in life. Physicians treating the foot and ankle must include osteosarcoma in their list of differential diagnoses to exclude when vague symptoms involving deep pain and edema present. It is critical to prevent misdiagnosis and delayed treatment with this form of tumor.
