A case of erythromelalgia with gastrointestinal dysautonomia treated with immunoglobulin: A case report

Abstract

An 18-year-old female with a history of atopic march, hyperhidrosis, and eosinophilic esophagitis was diagnosed with erythromelalgia and gastrointestinal dysautonomia secondary to presumed autoimmune small fiber neuropathy. The patient experienced significant clinical improvements after the initiation of intravenous immunoglobulin therapy, supporting an underlying autoimmune disorder.
