RESUMEN
Palpable migratory arciform erythema is an entity of unknown etiology, with few published cases in the literature. The clinical and histopathological features of this disease are difficult to be distinguished from those of Jessner’s lymphocytic infiltration of the skin, lupus erythematous tumidus and the deep erythema annulare centrifugum. We describe here the first two Brazilian cases of palpable migratory arciform erythema. The patients presented with infiltrated annular plaques and erythematous arcs without scales. These showed centrifugal growth before disappearing without scarring or residual lesions after a few days. They had a chronic course with repeated episodes for years. In addition, these cases provide evidence of a drug-induced etiology.

A tatuagem é definida como deposição de pigmento intencional ou acidental na pele. Os pigmentos têm sido associados a diversas dermatoses, como a dermatite de contato alérgica, a dermatite liquenoide e as reações fotoinduzidas, granulomatosas, sarcoídeas e pseudolinfomatosas. Enfocam-se os diversos tipos de reações aos pigmentos e a importância de reconhecê-los clinicamente. São relatados dois casos: um de dermatite liquenoide sobre o pigmento vermelho e outro de pseudolinfoma sobre os pigmentos vermelho e lilás e de reação fotoinduzida sobre o amarelo. A remoção geralmente requer múltiplos tratamentos, e a maioria não retira as cores completamente.
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.
