Tattoo-associated pseudolymphomatous reaction and its successful treatment with hydroxychloroquine

Tattooing has become increasingly popular in today’s society, although it has been practiced for over 8000 years (1). Following this new fashion trend, physicians have documented an increasing number of tattoo-associated skin disorders.The most common dermatological tattoo compli-cations concern hypersensitivity reactions to tattoo pigments, for example, irritant and allergic contact dermatitis (2), development of lichenoid areas (1, 3–5), and granulomatous responses such as sarcoid granulo-mas or foreign body granulomas (1). Less frequently patients developing discoid lupus erythematosus have been reported (2).Pseudolymphoma confined to the tattoo area is an unusual tattoo reaction that, to the best of our knowledge, has been described in only seven cases in the literature (6–10). We report here a new case of pseudolymphoma developing in the green portion of a multicoloured tattoo, which was treated with a systemic anti-malarial drug.CASE REPORT
