Osteosarcoma of first metacarpal with bilateral lung metastasis: A rare case report

Abstract

Osteosarcomas of hands are rare, (<1%) and these cases differ in presentation and behavior compared to those in usual locations. Histological grade was the only significant single prognostic variable for risk of death. High-grade osteosarcoma of the hand should be treated similar to those in conventional sites with ablative surgery and neoadjuvant chemotherapy. Here, we report a case of high-grade osteosarcoma of the first metacarpal. World literature shows occasionally reported case of this site. Rarity of the lesion and creating awareness among surgeons about existence of such a lesion in smaller bones is our motto. This would prompt them for an early effort for proper diagnostic procedure and subsequent early treatment so that prognosis of this grave disease can be improved. In the present case, diagnosis was delayed and pulmonary metastasis was present at time of diagnosis. The patient is presently undergoing chemotherapy and under regular follow-up.
