Tattooing for ornamental purposes is an ancient practice that remains popular in modern times. Tattoos are encountered by the dermatopathologist either as incidental findings on skin biopsies or because of complications specific to the tattoo. ⋯ Infections with bacterial, viral and fungal species can occur after tattooing, sometimes after substantial delay. Atypical mycobacterial infections in particular are increasingly reported; special stains for mycobacteria should be performed and cultures recommended particularly when dense, mixed or granulomatous infiltrates are present.
