The many faces of lymphocytoma cutis

Cutaneous T Cell Pseudolymphoma at the Site of a Semipermanent Lip-Liner Tattoo

“…At the time of diagnosis, pseudolymphomas appear to have a benign biologic behavior and do not satisfy the criteria for malignant lymphomas [1] . Tattoo-induced cutaneous pseudolymphomas generally belonged to cutaneous B cell pseudolymphomas [1,2] . However, tattoo-induced cutaneous T cell pseudolymphoma has been reported previously [3,4] .…”

Cutaneous pseudolymphoma occurring after traumatic implantation of a foreign red pigment

“…(1,5) Although most cases are idiopathic, reported triggering factors include Borrelia burgdorferi infection, insect bites, drugs, acupuncture, trauma and vaccinations. (1,2) Common…”

“…(1,6,7) In view of reports of cutaneous pseudolymphomas progressing to true lymphomas, (1,5) close follow-up is recommended.…”

“…(1,2) Mercury-based red pigments in cosmetic tattoos have been implicated as a cause. (3)(4)(5) We report an interesting case of the development of cutaneous pseudolymphoma after accidental, traumatic implantation of a foreign red pigment.…”

T- and B-Cutaneous Pseudolymphomas Treated by Surgical Excision and Immediate Reconstruction

“…Topical or intralesional steroids, local radiation, argon laser, cryosurgery, interferon-a, thalidomide, immunosuppressive agents, nitrogen mustard, hydroxychloroquine sulfate, and surgical excision have been reported as treatments of idiopathic pseudolymphoma. 7,[13][14][15][16] A lesion suspected of being pseudolymphoma or malignant lymphoma should undergo an excisional biopsy that extends into the subcutaneous fat. A 4-mm punch biopsy often provides a specimen that is inadequate for accurate reading by the dermatopathologist.…”
