Introduction: Mesenchymal chondrosarcoma (MC) is a rapidly progressive sarcoma that predominantly impacts the bones. Making up only 3% of chondrosarcomas, about one-third of these tumours develop in extra-skeletal sites.
Case Presentation: The authors present a clinical case of a 42-year-old patient who was diagnosed with MC 8 years ago, now admitted to the hospital with a palpable epigastric mass.
