Red ear syndrome has been reported in the literature to have similarities to erythromelalgia with auricular involvement; however, the distinction between the two is controversial. Red ear syndrome has previously been classified as idiopathic (primary) or secondary, with headaches being the most common association in the idiopathic or primary form. We present a case of pediatric red ear syndrome with hand and foot involvement that we believe represents auricular erythromelalgia. In this report, we propose a classification system to unify the diagnoses of red ear syndrome and erythromelalgia and review the literature on pediatric cases of red ear syndrome.
Keywords: auricular; erythromelalgia; migraine; pediatric; red ear syndrome.
