Herpes compunctorum: cutaneous herpes simplex virus infection complicating tattooing

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.
