A case of nummular eczema treated with Mahwangyeongyojeoksodu-tang

Objectives: This study aims to report a case of nummular eczema improved by Mahwangyeongyojeogsodu-tang.Methods: The symptom changes of nummular eczema lesions were evaluated using the Eczema Area and Severity Index (EASI) and the Validated Investigator Global Assessment scale for Atopic Dermatitis (vIGA-AD™). Skin itching was assessed using the Worst Pruritus Numerical Rating Scale (WP-NRS), and sleep disturbance was assessed using the Visual analog scale (VAS). We retrospectively analyzed changes in each observation item according to clinical progress recorded in the electronic medical record system.Results: Using Mahwangyeongyojeoksodu-tang as a treatment intervention, nummular eczema that had persisted for 7 months showed improvement in subjective and objective evaluations after 35 days. A 2-year follow-up observation survey confirmed that there was no recurrence or worsening of nummular eczema.Conclusion: Mahwangyeongyojeoksodu-tang may be one of the selective therapeutic interventions for nummular eczema that shows limitations in steroid therapy.
