Clavicular and meningeal alveolar soft part sarcoma: An unusual case and literature review

Introduction: Alveolar soft part sarcoma (ASPS) commonly arises in the soft tissue of the lower extremities. Primary bone involvement is rare. Methods/Results: We report a 23-year-old male who presented with pathologic fracture of the clavicle, and diagnosis of clavicular ASPS. Workup demonstrated a lumbar meningeal mass, also involving the vertebral bodies. Conclusions: Few cases of primary bone ASPS have been identified. Most common primary bone involvement includes the fibula, ilium and tibia. Likewise, meningeal involvement is quite rare. In summary, primary bone ASPS is rare and may involve the clavicle. Meningeal involvement is likewise rare, and presumably represents metastatic spread.
