title: Sensitization to methylenedianiline and para-structures.
abstract: A toxic-allergic skin reaction of the face, neck and arms due to accidental contact with methylenedianiline (syn: 4-4'-diaminodiphenylmethane) is reported in a cleaner at a chemical plant. Patch tests revealed sensitization to chemicals of the para-group. Earlier exposure to it was unlikely. Previous sensitization to related chemicals and possible cross-sensitization was considered to be the primary cause of the allergy and the clinical manifestations.
