A Rare Location of Osteosarcoma in the Cuboid Bone: A Case Report.

ABSTRACT

CASE In this case report, we describe a patient with left foot pain whose magnetic resonance imaging revealed a destructive tumor of the left cuboid bone. A biopsy of the tumor confirmed an osteoblastic osteosarcoma of the cuboid, and the patient was treated with chemotherapy followed by a below-the-knee amputation. CONCLUSION: There are only a handful of cases reporting osteosarcoma of the cuboid bone, and challenges remain in properly diagnosing the lesion to recommend the best course of treatment.
