After exposure to the sun, an erythematous, edematous, pruritic allergic
reaction developed at the site of a 22-year-old man's new tattoo. In addition
to photoallergy--as seen in this patient--direct allergy to the dyes in the
tattoo can produce an adverse reaction.
Complete removal of the pigment using either excisional surgery or
carbon dioxide laser is required. Nd:YAG laser or alexandrite laser may not
remove all the pigment. The patient underwent carbon dioxide laser tattoo
removal with good results.
