Allergic contact dermatitis from infant formula in an adoptive mother using a supplemental nursing system: The first case.

The article discusses a case of allergic contact dermatitis in an adoptive mother who developed eczema on her nipples, areolas, and fingers after using a supplemental nursing system (SNS) with infant formula to breastfeed her adopted baby. Patch testing revealed a positive reaction to the formula and nickel, with suspicions raised about metal contamination during formula preparation. The patient's eczema healed with corticosteroid treatment, and she remained lesion-free during a 14-month follow-up. This case underscores the importance of considering ACD from infant formula as a potential cause of nipple eczema in breastfeeding mothers, especially those using SNS. [Extracted from the article]
