An Atypical Migration Pattern of Tattoo Pigment

Unwanted diffusion of pigment past the original margins of a tattoo, termed "tattoo blowout," appears as a blurred rim classically surrounding the original tattoo borders. The darkened skin is visibly noted within hours to days following the tattooing procedure. Although this complication is not largely covered in literature, in prior cases, blowout has been shown to occur in areas of thin skin such as the dorsum of the foot. We present a rare presentation of tattoo blowout in a possible gravity-dependent pattern of pigment migration, occurring years after tattoo application. This atypical presentation highlights the knowledge gap that exists in the medical literature surrounding the mechanism of tattoo blowout and reinforces that physicians should be aware of these potentially poor aesthetic outcomes.
