title: Is micropapular sarcoidosis tuberculosis?
abstract: Three cases of micropapular sarcoidosis are reported. Two of the cases have a history of tuberculosis and all three cases have atypical patterns of Kveim and Mantoux reactivity. The similarities between this form of sarcoidosis and lichen scrofulosorum or lichenoid tuberculid are observed and the evidence is presented for a tuberculoid aetiology in certain forms of sarcoidosis.
