TLDR Eosinophilic esophagitis may trigger alopecia areata in some patients.
Alopecia areata (AA) was found to be associated with atopy in 10-22% of patients, which was twice the prevalence in the general population. The study presented a patient with AA who also had eosinophilic esophagitis (EoE), an allergic disorder characterized by esophageal dysfunction and intraepithelial microabscesses. The authors proposed that EoE should be considered an atopic disease and a potential trigger for AA in affected patients.
