Tattoo rates in the United States have been rising in recent years, with an expected concomitant rise in tattoo-associated complications. Tattoo complications range from cutaneous localized and generalized inflammatory eruptions, to local bacterial or viral infections, and finally to infectious endocarditis and hepatitis. Many complications may be avoided with proper counseling prior to tattoo placement, especially in high risk individuals. It is important for physicians to be able to recognize and diagnose complications from tattoos to avoid morbidity and possible mortality.
