화폐상 습진(Nummular eczema) 병변으로 내원한 환자에게 고문자적 해석을 바탕으로 當歸回逆湯을 진단하여 다음 결론을 얻었다. 1. 화폐상 습진(Nummular eczema) 환자에게 當歸回逆湯을 30일 투약 후 DLQI 18점에서 0점, VAS 10에서 1로 개선되었다. 2. 『傷寒論』351條에서 厥, 細를 피부병변부 발생의 원인과 관계된 병리적인 단어로 추론하고 고문자적으로 해석하여 當歸回逆湯을 투여하고 치료함으로써 한의학적 임상 진단 방법을 구체화할 수 있는 가능성을 제시하였다.

Objective: This study aimed to report the improvement of a patient with nummular eczema treated by herbal medication based on the Shanghanlun disease pattern identification diagnostic system (DPIDS). Methods: According to the Shanghanlun DPIDS, the patient was diagnosed with Reverting yin disease (provision 351), and was administered Danggwihweyeok-tang for 30 days. The result of administration was evaluated by the Dermatology Life Quality Index (DLQI) and a visual analog scale (VAS). Results: After administration of Danggwihweyeok-tang for 30 days, the DLQI decreased from 18 to 0 and the VAS decreased from 10 to 1. Conclusions: The affected skin region recovered. This case report suggests that the words “厥” and “細” in the 351^st Shanghanlun provision refer to physical and internal causes of nummular eczema.
