Giant cell rich osteosarcoma of the cuneiforms

Osteosarcoma is the commonest primary malignant bone tumor in children and adolescents. Giant cell rich osteosarcoma is a rare subtype of conventional osteosarcoma. Osteosarcomas commonly involve the metaphysis and meta-diaphysis of long bones. We report a 19-year-old girl with giant cell rich osteosarcoma of the medial and intermediate cuneiform bones. Even though, giant cell rich osteosarcoma is frequently mistaken for osteoclastoma of the bone; age of onset, location of lesion, radiological features, and histological characteristics on a high power field helps to differentiate the two conditions. Appropriate and early diagnosis of this variant possibly averts severe morbidity and mortality to the patient. Nonmetastatic osteosarcomas in the foot have better prognosis and are amenable to limb salvage surgeries.
