We report a case series of 38 children with suspected allergic contact dermatitis (ACD) to nickel who presented with prominent subumbilical and periumbilical papules and a generalized, lichenoid papular dermatitis resembling an id reaction. We speculated that this was an ACD to nickel and performed patch tests in 9 (24%) of these patients. All 9 (100%) patients had positive patch test results for nickel, thus confirming the diagnosis.
