A tattoo granuloma with uveitis (TAGU) without sarcoidosis.

Tattooing is associated with a handful of potential complications. Short-term complications such as pain, pruritus, erythema, or swelling at the tattoo-site commonly occur from local skin trauma. Long-term complications tend to involve infections or immune-mediated reactions such as sarcoidosis. The sudden development of a papulonodular skin eruption affecting a particular pigment in a tattoo is often the initial manifestation of undiagnosed sarcoidosis in these patients. However, in a small number of individuals, the granulomatous change in the tattoo and uveitis occur in the absence of any evidence of sarcoidosis. A case is presented of a tattoo granuloma with uveitis (TAGU) without sarcoidosis.
