Case 1. After using infliximab, alopecia areata developed and worsened. At her first visit to our department, hair loss spots (2 cm in diameter) were scattered on the temporal and occipital regions of the head (a). In the past 5 months before her first visit, the skin eruptions on her ears had been worsening. Exudative erythema and crusts were found on both ears (b). After her medication had been switched to vedolizumab, symptoms of both alopecia areata and atopic dermatitis improved without any specific medication (c, d).
