title: Pseudolymphoma occurring in a tattoo.
abstract: Pseudolymphomas are reactive inflammatory disorders due to different causative agents. Only a few cases of pseudolymphomas resulting from a tattoo have been described in the literature. We describe a 34-year-old woman with a nodular infiltrate limited to the red areas of a tattoo which had been administered 6 years before. Topical treatment with steroids had not been successful. As a result of clinical, histopathological and immunohistochemical findings and genotyping (polyclonal proliferation) the diagnosis of pseudolymphoma was made and total excision of the lesion was performed.
