Periprosthetic breast capsules can develop synovial metaplasia, a condition mimicking the synovial membrane. This change, likely triggered by implant movement, is common in textured breast implants.

Area of Science:

  • Pathology
  • Histology
  • Biomaterials Science

Background:

  • Periprosthetic capsules form around breast implants.
  • Textured implants are associated with specific capsule changes.
  • Synovial metaplasia is a poorly understood phenomenon in this context.

Observation:

  • Three cases of periprosthetic breast capsules with synovial metaplasia were analyzed.
  • Histology revealed a cellular layer resembling synovial membrane, lacking a basement membrane.
  • Cells showed differentiation into giant multinucleated cells.

Findings:

  • Immunohistochemistry and ultrastructure confirmed histiocytic origin of the cells.
  • Cells exhibited advanced differentiation towards synovial membrane elements.
  • Synovial or synovial-like metaplasia was identified in a significant portion of textured implant capsules.

Implications:

  • The findings suggest mechanical forces, specifically implant movement, are the likely cause of synovial metaplasia.
  • Understanding this metaplasia is crucial for evaluating the long-term behavior of breast implants.
  • Further research into implant-tissue interactions is warranted.
