Core Tip
Core tip: Cystic pancreatic lesions are more commonly recognized and diagnosed with developing imaging technologies. Metastasis to the pancreas from osteosarcoma is unusual, but has been reported in terms of solid pancreatic masses. This case report shows that metastasis should remain in the differential diagnosis even for primarily cystic pancreatic lesions.
