Lee, Lee, Jo, and Park: A Case of Chronic Nummular Dermatitis Improved by Hwangryunagyo-tang



This study aims to report a case of chronic nummular dermatitis improved by Hwangryunagyo-tang.


The patient in this study was a 15-year-old female, who visited our hospital with symptoms such as redness, erythema, papule, excoriation, scale, exudation, crusting, lichenification, and pruritus of the extremities and trunk. Considering that the skin lesions were coin-shaped and persisted for more than 6 months, the patient’s symptoms were diagnosed as chronic nummular eczema. Based on the patient’s symptoms and overall condition, Hwangryunagyo-tang was prescribed.


Approximately 4 months after administration of Hwangryunagyo-tang, the exudate disappeared, and overall skin symptoms improved, from objective score 33.7 to 6.6, leaving only slight scale, dryness, and pigmentation. As the pruritus of the skin lesion decreased from numeric rating scale 8 to 1, the patient’s sleeping condition also improved from numeric rating scale 9 to 0.


This study is significant in that the symptoms of chronic nummular dermatitis were effectively improved after administration of Hwangryunagyo-tang.
