SYNOVIAL METAPLASIA OF A PERIPROSTHETIC CAPSULE SURROUNDING A POLYURETHANE FOAM BREAST PROSTHESIS

A 43-year-old woman underwent two-stage bilateral reconstruction mammo plasty using silicone-filled, polyurethane foam-covered breast implant s. The permanent implants were later removed, The periprosthetic capsu le demonstrated synovial metaplasia by light and electron microscopy, Synovial metaplasia is believed to be induced by the physical and chem ical characteristics of the prostheses and may have important clinical implications in reducing capsular contracture and increasing host acc eptance of implantable biomaterials.
