title: Reactions to the different pigments in tattoos: a report of two cases.
abstract: Tattoos are defined as the intentional or accidental deposit of pigment into the skin. These pigments have been associated with various dermatoses such as allergic contact dermatitis, lichenoid dermatitis, photoinduced reactions, and granulomatous, sarcoid and pseudolymphomatous reactions. The objective of this report was to describe the various types of reactions to pigments and the importance of recognizing them clinically. Two cases are reported: one of lichenoid dermatitis resulting from a reaction to the red pigment of a tattoo and the other of a pseudolymphoma resulting from a reaction to red and lilac pigments and a photo-induced reaction to a yellow pigment. Removal generally requires multiple forms of treatment, most of which fail to remove the colors completely.
