Necrobiosis lipoidica diabeticorum in a tattoo site.

Background:Trauma is an immediate triggering factor in the development of necrobiosis lipoidica diabeticorum (NLD). NLD has previously never been documented in a tattoo site.Objective and Conclusion:Here we report an otherwise healthy 35-year-old woman with an area of NLD located in a tattoo site. Initial injection with intralesional triamcinalone acetonide showed no benefit. Subsequent application of betamethasone valerate cream did not lead to improvement of the lesion.
