Key result
Stainless-steel and titanium pelvic implants linked to angiosarcoma after 33 years, suggesting galvanic corrosion.
Why the study?
Literature is sparse regarding secondary deep soft tissue angiosarcoma, particularly cases forming around foreign bodies such as orthopedic implants.
Population
A 59-year-old Caucasian male with orthopedic implants placed 33 years ago

Warrants vigilance for sarcoma at long-term dissimilar-metal implant junctions; hypothesis-generating for galvanic corrosion in secondary oncogenesis.
This case highlights a rare presentation of secondary deep soft tissue angiosarcoma arising at the juncture between two orthopedic implants of different compositions, suggesting a possible effect of galvanic corrosion.
Morales et al. (2026) studied this question. A high-grade angiosarcoma developed at the juncture of 33-year-old stainless-steel and titanium pelvic implants, suggesting galvanic corrosion as a potential etiology.
