Allergic contact dermatitis from fluocortolone, flucocortolone pivalate and fluocortolone caproate.
Two patients with contact allergy to Ultralan preparations are reported. Each Ultralan preparation contains two of three related fluocortolone derivatives. The first patient reacted to all three derivatives. The second patient reacted to flucortolone and when retested 4 months later also to fluocortolone pivalate but ot to flucortolone caproate. The negative reaction to fluocortolone pivalate at the first examination was probably false negative due to a low test concentration. In order to avoid false negative patch test reactions the fluorinated steroids should possibly be applied in concentrations higher than 1%. No cross sensitivity to the other steroids for topical use was found.
