(A) Tattoo skin section (0.5 μm) stained with toludine blue. Cells containing green tattoo dye in their cytoplasm (black arrow) surrounded a blood vessel. (B) Electron microscopy of a tattoo showed that dye particles (red arrow) were membrane bound (blue arrow) within the cytoplasm of a cell with multiple microvillus protrusions (green arrow). (C and D) Cells containing green tattoo dye particles stained for CD163 (D) but not BDCA-1 (C). Scale bar: 10 μm (A, C, and D); 200 nm (B).
