Of 73 adult patients attending a clinic specially provided to treat patients with atopic dermatitis, 31 (42%) showed one or more positive patch reaction on contact testing. There was a striking female preponderance in the patch test positive group (26F:5M) in contrast to those with negative test results (9F:17M). The commonest allergens identified were fragrances in 13 patients, nickel (7), rubber (5), lanolin (4) and formaldehyde (3). In 21 patients, topical preparations, cosmetic or medically prescribed, could be implicated. Contact sensitivity seems to be relatively common in adult patients who have a continuing problem with their atopic dermatitis. Recognizing this sensitization may be important in their management.
