[Pecilocin allergy]

In 1975 there were a total of 44 patients in the author's practice with a history of treatment with pecilocinum (Variotin). These patients were patch tested with pecilocinum, and seven were found to be allergic to this drug. In three of them the skin disease had been caused or exacerbated by pecilocinum. In the other four patients the allergy to pecilocinum must be regarded as an "immunological scar".
