title: Occupational allergic contact dermatitis from olive oil in a masseur.
abstract: Contact allergy to olive oil is considered rare. There are 20 cases of contact allergy to olive oil described, and 3 of these had an occupational hand eczema as a result of olive oil. We describe a masseur who was allergic to olive oil, resulting in an occupational hand eczema. Both patch tests and a use test with olive oil was undertaken. An oral provocation with olive oil was also performed. Both patch tests were positive, as was the use test after 2 days. The oral provocation test was negative. Despite contact allergy to olive oil being rare, sensitization occurs. The external use of olive oil should be discouraged, at least in masseurs, when used under occlusion, and in long-standing dermatoses.
