To the Editor: A 30-year-old man presented with pain, swelling and discharge from lesions on his left arm. He had undergone extensive tattooing on the arm 3 days earlier at a commercial tattoo operation, where single-use needles were used, with initial drawing of lines followed by additional shading. The patient complained of severe neuropathic pain in the arm, which was greater than would be expected from uncomplicated bacterial cellulitis. He did not give a history of oral or genital herpes and had previously been tattooed without complication. On presentation, the patient had a low-grade fever (37.9°C), a heart rate of 80 beats/min and blood pressure of 130/80 mmHg. He had no neurological deficit.

Vesicular lesions were visible in the region of the tattoo marks, predominantly affecting areas of shading and with minimal spread outside tattooed areas (Box). A bacterial swab of the lesions grew methicillin-sensitive Staphylococcus aureus, and a polymerase chain reaction test of vesicular fluid was positive for herpes simplex virus type 1 (HSV-1). The patient was commenced on intravenous flucloxacillin (1 g four times daily) and oral famciclovir (250 mg three times daily). He required ongoing inpatient management for pain relief. Five days after development of the lesions, HSV-1 serology demonstrated positive results for IgM and IgG. An HIV test was negative. The patient’s lesions slowly resolved, and he was discharged 7 days after admission.

Most concerns regarding infectious complications of tattooing have focused on transmission of blood-borne viruses, but superficial infections with other pathogens have also been described.1 The personal care and body art industries are regulated in Australia to minimise the transmission of blood-borne infection,2 and most state and territory authorities also publish infection control guidelines.

Herpes dermatitis is often confused with bacterial infection, although co-infection may occur. This distinction is clinically important, as antibiotics and surgical debridement are not usually required for herpetic infections, and herpetic lesions may recur. Secondary herpetic infection complicating skin disease is most commonly associated with eczema (eczema herpeticum) or other skin diseases (Kaposi’s varicelliform eruption), and minor skin trauma, such as in herpetic whitlow or herpes gladiatorum.3,4 We are not aware of any previous reports of herpetic infection complicating tattoo placement.

The distribution of herpetic lesions in our patient suggested that the needle used for tattoo shading became contaminated with HSV-1 during the course of tattoo placement, but it is also possible that superinfection occurred through damaged skin after the procedure. We propose the term “herpes compunctorum” to describe this condition.
