The complications associated with the hemi-silicone implants of the foot have been well documented. Reasons for their failure are many. In the past, there has been an overuse of these devices without strict adherence to their proper indications. Today, these implant failures are being manifested by extremely unusual pathology. Although silicone has not been shown to be carcinogenic, the florid reaction seen in this case demonstrated a degree of "malignancy" that may have incapacitated the patient.
