Metal implants are commonly used in orthopedics for treating degenerative conditions and fractures. These materials are generally considered non-toxic.

In this report, we present the case of an unclassified high-grade sarcoma in a 51-year-old patient to highlight the rarity of this condition and the challenges associated with its diagnosis.
