Prurigo nodularis (PN) is a chronic inflammatory skin disease that affects the quality of life of patients and is classified in the ICD-10 as a group of chronic lichen simplex and itchy skin diseases (ICD-10/L28) with an incidence of approximately 36.7-148.53 per 100,000 people. The pathogenesis of PN is closely related to type 2 inflammatory response. There are no standardized treatment guidelines for this disease, and traditional anti-pruritic treatment regimens often fail to control the vicious pruritic-scratch cycle in PN and have a poor safety profile. Traditional treatment options for PN include oral antihistamines, thalidomide, and topical hormones, calcium phosphatase inhibitors, and other treatments. However, traditional treatment options often suffer from poor pruritus control and high side effects. A patient with prurigo nodularis was admitted to our hospital who responded poorly to routine topical glucocorticoids and other drug therapies and relapsed after discharge from treatment. After readmission, the patient was successfully treated with dupilumab, a biological agent targeting interleukin-4/13. The patient's rash was significantly flattened, and the pruritus NRS score was significantly decreased. In this case, successful treatment of refractory PN with dupilumab could provide new ideas for treatment.
