ABSTRACT

Tattooing has been associated with a variety of complications including inflammatory and granulomatous reactions, transmission of infections, and neoplasms. We report a case of a 24-year-old male who presented with a 2-month history of an erythematous nodule involving a newly made tattoo on the right leg. An excisional biopsy was performed and the histopathological evaluation was consistent with dermatofibroma. Only three cases of dermatofibroma associated with tatooing were reported in literature. We report an additional case and review the literature regarding cutaneous reactions to tattoos.

f04: Extracellular deposits of black pigment

Mentions: Examination of the hematoxylin-eosin stained histological sections of an excisionalbiopsy revealed nodular dermal proliferation of fibroblast-like cells embedded in adense collagen matrix. These cells displayed an irregular arrangement, but nocytological atypia. The overlying acanthotic epidermis showed basal hyperpigmentation.In addition, extracellular deposits of coarse black pigment were observed, particularlyabove the spindlecell proliferation (Figures 2,3 and 4).
