Pseudolymphoma tattoo-induced.

Tattooing has become more and more popular in today's society. The most common dermatological tattoo complications are represented by hypersensitivity reaction to tattoo pigments like irritant and allergical contact dermatitis, development of lichenoid areas and granulomatous responses, such as sarcoid granulomas or foreign body granulomas. Less frequently patients developing discoid lupus erythematous have been reported. Pseudolymphoma is an uncommon reactive lymphocytic proliferation mimicking the histological and clinical features of a malignant skin lymphoma. We herein report a pseuldoymphoma limited to the red area of a multicolour tattoo of the leg.
