Definition / general
  • Important to document gross and histologic findings associated with implant related specimens
Clinical features
Case reports
Microscopic (histologic) description
  • Chronic inflammatory response (plasma cells, B and T cells and foamy macrophages) with fibrotic capsule around the implant causing contracture of prosthesis (Aesthetic Plast Surg 2010;34:481)
  • Lining cells may resemble synovium (synovial metaplasia, Mod Pathol 1994;7:310)
  • Gel may seep through intact implant shells
  • May have foreign body reaction with sinus tracts
  • Numerous cystic spaces and vacuoles may exist where silicone dissolves during processing
