Figure 1 (a,b): Histology of the fibrous capsule at optical microscopy (OM) without (a) and with (b) polarized lenses. A 53 years-old female with breast implant for 7 years. OM showed a fibrotic wall with foreign body type reaction with giant cells, histiocytic reaction with synovial metaplasia without atypia (green #), and discrete nonspecific focal lymphocytic infiltrate without atypia (red *). At polarized lenses, non-polarized refringent material was observed inside these vacuoles, compatible with silicone (yellow arrows)
