Multiple epidermal cysts occcurring in a tattoo

ABSTRACT
In decorative tattooing, pigment is introduced into the skin with needles or a tattoo gun to create a picture, motif or symbol. Various skin reactions have been reported in association with tattoos. These include acute inflammatory reactions, eczematous hypersensitivity reactions, pseudolymphomatous reactions and skin infections. We present a 24-year-old Malay man who developed multiple epidermal cysts a month after tattooing. To the best of our knowledge, this is the first case in the literature of epidermal cysts occurring after skin tattooing.
