Abstract

Extraskeletal osteosarcoma (ESOS) is a rare mesenchymal soft-tissue neoplasm that accounts for approximately 1% of all soft-tissue sarcomas. Over 70% of these malignant tumor progress to local recurrence and metastasis. It commonly metastasizes to the lungs, lymph nodes, bone, and skin and has a poor survival outcome. Cutaneous metastasis is exceedingly rare and known to be a sign of widespread metastases. We present a 57-year-old woman who presented with a rapidly growing protuberant mass on the scalp that was finally diagnosed as metastatic ESOS from a primary pancreatic ESOS. To our knowledge, there has been no reported case of pancreatic ESOS metastasizing to the scalp.
