title: Pseudolymphomatous reaction to tattoos. Report of three cases.
abstract: Three cases with pseudolymphomatous hypersensitivity reaction to tattoo pigment are described. One of the cases showed histologic features of Spiegler-Fendt pseudolymphoma. Awareness of this type of reaction to tattoo pigment can help prevent erroneous diagnosis of lymphoma. Several published reports are cited in which pseudolymphomatous reaction to tattoo pigment was erroneously diagnosed as lymphoma.
