Overview

Tattoos, as accurately stated, are a means of displaying art and a story on any area of the body; yet, if they are not properly cared for, they may result in a number of infections or complications

In most cases, contaminated ink or equipment is the cause of a tattoo infection.

Proper diagnosis is important to guide the right treatment for tattoo infections.

Introduction

One way to beautify the body is with a tattoo. Generally speaking, tattoos are applied for a variety of cultural reasons (cultural identity or group affiliation), medical (showing the location of a radiation port), cosmetic (eyeliner, eyebrows, lips, and skin tones) and painful recreation in some cases.²

Artists use handheld machines with at least one needle repeatedly penetrating the skin.

The practice of body arts has become common in today's society.

Inks may be made from iron oxide, metal salts, and plastics. 

Poor hygienic standards and careless procedures can result in localised infections and even life-threatening conditions.

Local allergic reaction patterns

• Papulo-Nodular Pattern: ­­­Occurs due to pigment overload or needle trauma. This pattern is very common and especially noted in black tattoos. There is elevation of the entire tattoo
• Excessive Hyperkeratotic Pattern: occurs in red tattoos. This happens when there is escape of the pigment to the epidermis, causing inflammation
• Ulcero-Necrotic Pattern: Aggressive inflammation is directly followed by tissue necrosis and seen in red tattoos
• Lymphopathic Pattern: Tattoo pigment injected deep into the dermis may enter the surrounding skin and produce a stain in the direction of the lymph flow. This can block lymph vessels and tissue swell can occur.
• Neurosensory pattern: tattoos can cause itching and pain without showing clinical symptoms
• Scar pattern: trauma due to multiple needles can cause hypertrophic scar

Allergic reactions

Pigments in tattoo ink can slowly break down over time, releasing small amounts of chemicals that may cause harmful reactions such as allergies. 

Allergic reactions are very often seen in red tattoos or in shades of red affecting every part of the tattoo of that particular color at the same time, with ‘plaque elevation

Therefore, a hapten that develops inside the skin over a longer period of time (months or years) causes allergic reactions rather than an allergen that is immediately present in the tattoo ink stock product.

Chronic allergic reactions in red tattoos are mostly unresponsive to topical corticoid and best treated with dermatome shaving with complete removal of the hapten concentrated in the outer dermis.¹

Signs of an infected tattoo

• Redness in the tattoo area
• Pain at the site after the first week
• Pus formation
• Fever
• Chills and sweating

Source of infection

Tattoo-associated infections include not only bacteria, mycobacteria, and viruses, but also fungal infections.⁵ 

It includes four main sources.

• Inadequate cleanliness throughout the tattooing process
• Contamination of tattoo ink with harmful microbes
• Poor healing and follow-up procedures
• In some cases, tattooists may unknowingly carry infections if proper hygiene is not followed

Bacterial infections

Acute bacterial infections are common and usually need antibiotic treatment.¹

Tattoo infections with bacteria, especially staphylococci, which may be resistant to multiple antibiotics, may be prominent and may progress into life-threatening sepsis.³

The numerous occurrences of microbial infections linked to tattoos, including the worldwide Non-Tuberculous Mycobacteria outbreaks, have greatly increased public health concerns worldwide and raised awareness of tattoos as a severe public health concern.⁷

Staphylococcus, Streptococcus, Pseudomonas, Clostridium, and even tetanus infections are examples of bacterial infections. Atypical bacterial infections include commensal mycobacteria, tuberculosis, and leprosy. 

Nowadays, tattoo ink supplies are still composite, containing a variety of chemical impurities and unidentified substances. ³

Infections with mycobacteria progress slowly. They are frequently brought on by tainted tap water that was used to dilute ink.

A polymicrobial infection after tattooing refers to an infection caused by multiple pathogens simultaneously.⁷ 

A rash with redness, swelling, and papules in the tattoo area is one of the symptoms. Other symptoms include a high temperature, poor overall health, illness and damage of important organs, and, if left untreated, death. 

Treatment options

• Pain and inflammation can be reduced using paracetamol and non-steroidal anti-inflammatory medications
• Medication that contains antihistamines can lessen allergic reactions, the antibiotic cream is intended to stop small wounds from getting infected
• Cephalexin, clarithromycin, ciprofloxacin, and amikacin are examples of oral antibiotics that can be given

Viral infections

Infections caused by viruses include herpes, HIV, and hepatitis B and C.

Viruses that cause local infections include condylomata, molluscum, and warts.

Localised to the tattoo ink, tattoo-associated viral infections can be cutaneous.

Human immunodeficiency virus (HIV) and hepatitis are two systemic viral infections linked to the tattoos.⁴ 

Hepatitis B infection

Interventions include

• Hepatitis B vaccination for all
• Information for those who are inclined to get tattoos
• Creation of tattoo safety initiatives

Hepatitis C Infection

• Tattoo-related hepatitis C transmission is prevalent among intravenous drug users, inmates, and veterans 

Herpes simplex virus infection

Investigators coined the term herpes compunctorum.⁴ 

They could not completely rule out the potential that the damaged skin became superinfected with the virus during the treatment, the investigators hypothesised that the needle had become contaminated with HSV during the tattooing.

Treatment

• Systemic antiviral and empiric antibacterial (cloxacillin, one gram twice daily) therapy, and topical chlorhexidine was initiated for five days.
• Topical antibiotic ointment

Treatment of Viral warts restricted to tattooed areas

• After applying topical methyl aminolevulinate (MAL) to the skin for three hours, the epidermodysplasia verruciformis lesions can be illuminated with a red light source as part of photodynamic therapy
• Cryotherapy, using liquid nitrogen, resulted in ablation of most or all the warts
• SADBE contact immunotherapy involves sensitisation
• The wart is 80% removed with one session of ablative erbium: yttrium aluminium garnet (YAG) laser treatment; the remaining lesion disappears after 12 weeks of applying 5% imiquimod cream every day⁴ 

Molluscum contagiosum

Molluscum contagiosum associated with tattoos first occurred two to twenty-four weeks (median, twelve weeks) following the tattoo.

Curettaging the viral lesions is possible.

Smallpox virus

Both the tattoo and the vaccine are thought to produce a cutaneous immunocompromised district of local immune dysregulation that increases the likelihood of cutaneous diseases or adverse skin events developing in the afflicted area.

It is best to wait until the vaccination location has healed before getting any fresh tattoos. ADD CITATION

Fungal infections

Tattoos may become infected with fungi. These comprise systemic mycoses in addition to dermatophyte infections (tattoo-associated tinea).The most common location for the superficial fungal infection associated with tattoos was an extremity covered in black ink. Usually, the dermatophyte infection shows up as a red, scaly, or non-scaly infection.

Tinea develops during tattoo healing, usually within one month of inoculation.⁵ 

Contaminated tattoo ink, skin injuries from tattoo needles, non-professional tattoo inoculation, diseased tattooing tools and/or ink in an immunocompromised host, and contaminated ritual tattooing tools and dye are among the causes.

Sporotrichosis, an implantation mycosis, occurs through traumatic inoculation and reported in people with tattoos.⁶ Spore inhalation can result in systemic fungal diseases. It has been hypothesised that the inoculation technique used by the patient or by an amateur tattoo artist is the infectious cause of the systemic fungal infection linked to tattoos.⁵ Contaminated ink was the only confirmed cause of the systemic fungal infection. Systemic fungal infections linked to tattoos may be treated with antifungal medication. The time span between the inoculation and the patient's discovery of the systemic fungal lesion within the tattoo ranged from a few days to 69 months.⁵ 

Treatment

• All patients with tattoo-associated tinea experienced full dermatophyte remission after receiving topical and/or oral antifungal medication
• The application of topical corticosteroid cream may cause tinea incognito, an unusual manifestation of dermatophyte infection
• The 0.1 percent triamcinolone cream can be advised 2% percent ketoconazole cream twice daily to the affected area can be prescribed for 4 weeks
• The duration of the tattoo from inoculation until the patient became aware of the dermatophyte lesion within the tattoo varied from six days to nearly six years⁵ 
• Treatment of tattoo-associated tinea involved both topical and oral antifungal drugs
• The topical antimycotic therapy included amorolfine cream
• Miconazole cream for 3 weeks, terbinafine one percent cream for 21 days, or luliconazole for 2 days
• Amorolfine cream daily for 4 weeks in case of red plaque can be given
• For painful necrotic papules Voriconazole can be given for 4 weeks
• In case of necrotic ulcer potassium iodide 500 mg thrice daily for 20 months
• In case of multiple firm, non tender papules saturated solution of potassium iodide, 5 drops three times daily for 3 weeks followed by 10 drops 3 times daily for 2 weeks
• Oral antifungal drugs included itraconazole 100mg , terbinafine, or griseofulvin

Summary

Tattoo care in clinics typically involves managing medical complications or helping people who no longer want their tattoos. The primary hazards connected to tattooing techniques in today's clinic include pyogenic infections with Staphylococcus, Streptococci, Pseudomonas, and E. coli, as well as the transmission of Hepatitis B and C.

The prevalence of microbiological illnesses linked to tattoos has gone up in spite of public health campaigns and greater awareness.

Interventions by healthcare professionals to stop the spread of these viruses during tattoo acquisition may help lower the incidence of virus-related illnesses in these people.

Since outbreaks affect a large number of people and entail many infections from a single pathogen source, they pose serious public health implications.
