Two patients with an inflammatory reaction in a red tattoo had histopathologic changes of lichen planus. The lesions demonstrated a lymphocytic bandlike infiltrate, liquefaction degeneration, acanthosis, hypergranulosis, and orthokeratosis and many hyaline bodies. Metal particles were observed in the region of the dermal-epidermal reaction. This probably is another example of the lichenoid reaction produced by delayed cellular hypersensitivity.
