Rare Extraskeletal Osteosarcoma in the Anterolateral Right Leg of a 37-Year-Old Man

Abstract not available. Introduction provided instead.

To our knowledge, the case described in this article is the first reported case of extraskeletal osteosarcoma localized to the anterolateral compartment of the leg. Although the location of the tumor in our case is unique, the clinical presentation, diagnosis, pathology, and treatment are consistent with prior reported cases. Here we highlight the unique radiographic and pathologic findings and the support for aggressive neoadjuvant therapy of this aggressive neoplasm. It is our hope that this case report provides a crucial review of the typical reported features of extraskeletal osteosarcoma and its management and raises important questions for future study of this rare neoplasm.
