Verruca Vulgaris Occurring on a Tattoo: Case Report and Review of Tattoo-Associated Human Papillomavirus Infections

Viral Infections Confined to Tattoos—A Narrative Review

Since ancient times, people have tattooed their skin for various reasons. In the past, tattoos were associated with low social status; nowadays, tattoos are very popular and are considered a form of art. However, tattoos are associated with various clinical problems, including immune reactions, inflammatory disorders, infections, and even skin cancer. Epidemiological and clinical data of infections on tattoos are scarce. Tattoo-related infections are mostly bacterial; only a few localized viral infections have been reported so far and are caused by molluscum contagiosum virus (MCV), human papillomavirus (HPV), and herpes simplex virus (HSV). In most cases, the lesions were strictly confined to the area of the tattoo. In this review, we have analysed reported cases of viral infections localized on tattoos and discussed the possible mechanisms involved in the occurrence of these infections.

Tattoo-Associated Viral Infections: A Review

Tattoos, a decorative form of body art, are produced by inoculating pigment into the dermis. Tattoo-associated viral infections can be cutaneous and localized to the tattoo ink; however, viral pathogens acquired during inoculation can cause systemic disease. A comprehensive review of the literature only reveals a limited number of published reports regarding patients with tattoo-associated cutaneous viral lesions. Cutaneous viral pathogens causing lesions to occur on a tattoo include herpes simplex virus (HSV), human papillomavirus (HPV), molluscum contagiosum, rubella, and vaccinia. HPV lesions (45 patients) and molluscum contagiosum (14 patients) are the most frequently reported tattoo-associated viral lesions; nearly all the patients were immunocompetent. HPV lesions included verruca vulgaris (29 patients), verruca plana (14 patients) and human immunodeficiency virus (HIV)-associated acquired epidermodysplasia verruciformis (two men). Hypotheses for tattoo-associated HPV lesions and molluscum contagiosum include a black ink-induced cutaneous immunocompromised district since the viral lesions all occurred in black or dark ink and the use of virus-contaminated instruments, pigment, or both during tattoo inoculation. Other sources of HPV include viral spread from a wart that is present but not associated with the tattoo site or virus transmission from the tattooist resulting from contact with a wart on an ungloved hand or HPV-containing saliva used to thin the pigment. Herpes compunctorum (three patients), vaccinia (two patients), and rubella (one patient) were less commonly reported. Blood borne viral pathogens associated with systemic manifestations – such as hepatitis B, hepatitis C and HIV – have also been acquired during tattoo inoculation; however, health care interventions have been adopted to attempt prevention of viral agent transmission during tattoo acquisition.
