Dx: Tatoo reactions
Clinically apparent inflammatory reactions to tattoos are quite rare and have been observed most commonly with the red dyes containing mercuric sulfide.
Tattoo reactions may be non-granulomatous or granulomatous. Non-granulomatous reactions may be lichenified or pseudolymphomatous and granulomatous reactions may be either of the sarcoidal type or the foreign-body type. Sometimes a sarcoidal granuloma in a tattoo may be the presenting manifestation of generalized sarcoidosis.
In this case, typical sarcoidal granulomas was seen in histopathological examination.
