慢性湿疹是皮肤科常见病，其病位在肌肤腠理，易涉及肺脾肾等脏腑器官。用药得当表证便可缓解，但病情易反复且愈发加重，难以完全根治。导师认为阳虚阴盛是本病的根源，外界风湿热邪是其诱因，强调引火助阳化内湿，散风清热祛外湿的治疗法则，诸邪驱尽，"痒、斑、烂、疹"等表证便可缓解，以"内外兼治、治法多变、变不离宗、宗为扶正"的思想贯穿诊疗的全过程，并且取得显著的疗效。笔者有幸跟随导师运用火针配合中医汤药治疗慢性湿疹，现将其临床实践作简要阐述，以飨读者。

Chronic eczema is a common dermatological disease, attacking the skin and often involving the lungs, the spleen, the kidneys and other organs. Proper medication can alleviate symptoms, but the condition is easy to repeat and aggravate, and it is difficult to completely cure. The author′s mentor believes that Yang deficiency and Yin excess are the root cause of the disease, and the external pathogen of wind, dampness and heat is the predisposing factor. He emphasizes the treatment principle of inducing fire to help Yang dispel internal dampness, and removing external dampness by dispersing wind and clearing heat. When all the pathogenic factors are eliminated, symptoms such as " itch, spot, rot and rash" can be alleviated. The idea of " internal combined with external treatment, and various therapies rooted in the principle of strengthening vital qi" runs through the whole process of diagnosis and treatment, which has achieved remarkable results. The author follows his mentor with honor in treating chronic eczema with fire needle combined with traditional Chinese medicine decoction, and the clinical practice is briefly introduced in the paper.
