Dx: Hypersensitivity to Tattoo Ink

alt 

 

Although an acute inflammatory reaction commonly occurs due to the soft tissue injury from the injected pigments, these usually resolve after several weeks. This patient had a hypersensitivity reaction to tattoo ink. It has been reported in the literature that tattoo allergy typically develops as a reaction to the ink in the tattoo (Hansan & Voutsalath, 2009) and most frequently is a contact dermatitis or a photoallergic dermatitis. The pigment dyes used for tattooing are prepared from metal salts. Red tattoo pigments, especially those made from mercury sulfide (cinnabar) cause the most frequent allergic reactions whereas yellow tattoo pigment (cadmium sulfide) is responsible for most photoallergic reactions. Other pigments utilized to create blue (cobalt aluminate), green (chromium oxide, lead chromate, or phthalocyanine) and black tattoos (logwood, iron oxide, or carbon) are much less common. Black tattoo pigment has been rarely reported to cause an allergic reaction. Phototoxic reactions may also occur in red tattoos due to the addition of cadmium, which is added in small amounts to intensify the red tattoo pigment.

Paraphenylenediamine (PPD) is a common allergen found in tattoo ink, temporary tattoo inks, and henna tattoos (Hansan & Voutsalath, 2009). Thimerosal is a mercury based chemical also reported to cause allergic contact dermatitis reactions in tattoos, however, mercury derived inks have been removed from the market due to their adverse side affects (Breithaupt & Jacob, 2008).

Allergic reactions tend to worsen over time; each exposure to the offending agent will cause an even worse reaction (Cowley, 2008). It is not uncommon for a patient to report having had previous tattoos with no complications, then reporting redness, nonhealing, pruritis with a recent addition of tattoo ink (Cowley, 2008). One person reported a new tattoo causing previously described symptoms in a new tattoo, as well as a 4-year-old tattoo with colored ink (Wiki, 2011). This person was treated with silver sulphadiazine dressings for 2 weeks with the older tattoo remaining intact with color and the new tattoo losing all color (Wiki, 2011).

The literature recommends acute treatment with antibiotic ointment, hydrocortisone creams, anti-itch creams and cold compresses; some dermatologists would also prescribed some form of systemic steroid for treatment (Cowley, 2008). Laser therapy is also an option in removing the offending agent by fragmenting the ink particles to a size where the body’s immune system can remove them (Cowley, 2008). Vitamin E, aloe vera and Qeurcitin (flavonoid) are also beneficial in aiding the immune system in rejuvenation and healing of skin (Cowley, 2008).

The wound cleansed with soap and water, and xeroform dressing applied to wound. The patient was referred to the dermatology clinic for a wound follow up as well as laser removal of the tattoo.

Cadmium sulfide can be used for many purposes, including materials for photo-resistors ; semiconductors; pure, inorganic photoconductors ; colorants for soaps, textiles, paper, plastics and rubber; x-ray fluorescent screens; body temperature detectors; rectifiers; transistors; photovoltaic cells; solar cells; and photoelectric radiation.
