Lesions on tattooed skin--a case study.

CASE STUDY: A man, 33 years of age, presented complaining of asymptomatic lumps on the tattooed skin of his right upper arm. The lumps appeared spontaneously 5 months after getting the tattoo. He had no significant past medical or surgical history. On examination, several 3–4 mm shiny, umbilicated papules were seen on the tattooed skin (Figure 1).Tests for human immunodeficiency virus (HIV), hepatitis B virus, hepatitis C virus and syphilis were negative and full blood examination was normal.
