(A) Skin (yellow dotted line), subcutaneous tissue and fibrous capsule over the implant (blue dotted line). (B) Fibrous capsule in greater detail, showing the biomaterial (birefringent appearance) inside a giant cell (blue arrow), the green arrow points to a vessel. (C) Fibrous capsule with intense neovascularization (green arrows) and multinucleated giant cells (red arrow).
