Lichenoid Delayed Hypersensitivity Reactions in Tattoos

Abstract
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.
