Patch testing with frullania during a 10-year period: hazards and complications.
Contact dermatitis from frullania mainly affects people living in the country. The 2 most frequent species in Europe, Frullania dilatata and Frullania tamarisci, do not cross-react: both species must be patch tested when frullania intolerance is suspected. Yet patch testing with frullania may be hazardous: 9 out of 37 cases recorded in Strasbourg correspond to active sensitization by the tests. Since routine testing is risky, only aimed testing can be recommended.
