Spontaneous resolution of a delayed granulomatous reaction to cosmetic tattoo.

A 27-year-old woman presented with linear, flesh-colored papules along her vermillion borders, 4 years after a cosmetic lip tattoo was applied. A biopsy of the lesion was performed and histology showed it to be a granulomatous reaction surrounding the tattoo pigment. Following the biopsy, the lesions began to resolve spontaneously within 4 weeks and were not noticeable at a follow-up review. Granulomatous reactions are rare after cosmetic facial tattoos and may respond to topical corticosteroids or laser ablation. We present a unique report of a delayed granulomatous reaction to a cosmetic tattoo completely resolving without any specific treatment.
