Osteoblastoma-like Osteosarcoma of the Cuboid: A Case Report

Osteosarcoma most commonly arises in the long bones of the skeleton, and rarely develops in the bones of the foot. We describe a patient who presented with left foot pain, whose radiographic evaluation revealed a lytic destructive mass in the cuboid bone. A biopsy showed an osteoblastoma-like variant of osteosarcoma and the patient was treated with preoperative chemotherapy and amputation. Osteosarcoma of the foot is uncommon and the literature reveals that it is often associated with a delay in diagnosis.
