Infections are nowadays directly related to the lack of asepsis and hygiene during the tattooing procedure or during the healing phase.
Patients with a known cutaneous disease should be warned of a potential risk of localization of their disease to the tattoo.
A skin eruption restricted to a tattoo may reveal sarcoidosis.
Patients with chronic conditions and/or impaired immunity should discuss with their physician about the possibility and when to have a tattoo.
