After a modified cutaneous patch test confirmed an allergic reaction to the implant, the device was surgically removed. The patient's symptoms were largely resolved 1 month after the removal of the device.Conclusion:CF-PEEK is a commonly used biomaterial in surgical implants. As far as we know, this is the first reported case of a hypersensitivity reaction to CF-PEEK.
