It has been used as an effective treatment for moderate to severe atopic dermatitis (AD) patients 1 . The adverse events include conjunctivitis, herpes simplex virus infection, and injection site reaction in varying proportions 1 . A 20-year-old male patient visited our hospital with pruritic erythematous plaques on the entire body from childhood. Based on the clinical findings, AD was diagnosed, and treatment with cyclosporine 100~200 mg was prescribed for more than one year. Because the cyclosporine treatment had not been effective, dupilumab administration was initiated. Subsequently, the patient’s clinical symptoms improved rapidly; however, after several months, he complained of facial flushing within a few minutes of consuming small amounts of alcohol (Fig. 1). He complained that this symptom lasted for less than one hour and had never occurred before treatment with dupilumab. No medications or topical agents were being taken concurrently. We considered the flushing in this patient as a rare adverse event that could occur after treatment with dupilumab, and the patient was educated to avoid alcohol consumption during the post-treatment period. Flushing is a transient erythema that most commonly occurs in the face because of an increase in cutaneous blood flow following vasodilation. One of the causes is the use of vasoactive substances, which include medication, food, and alcohol 2 . Alcohol flushing is caused by an increase in the acetaldehyde level due to deficiency or inactivity of aldehyde dehydrogenase 2 (ALDH2), which plays a major role in alcohol metabolism","PeriodicalId":94298,"journal":{"name":"Annals of dermatology","volume":"35 Suppl 1","pages":"S163-S164"},"PeriodicalIF":0.0,"publicationDate":"2023-05-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://ftp.ncbi.nlm.nih.gov/pub/pmc/oa_pdf/01/ba/ad-35-S163.PMC10608370.pdf","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"49687069","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

He presented with an erythematous thick scaly patch on his face, neck, and both hands and arms. He had a history of significant exposure to sunlight without using sunscreen. All lesions were restricted to sun-exposed areas and appeared one month ago. Histopathological examination revealed necrotic keratinocytes, epidermal spongiosis, liquefaction degeneration of the basal layer, interface dermatitis, solar elastosis, and upper dermal perivascular lympho-histiocytic infiltration. Based on clinical and histopathological findings, the skin lesion could be diagnosed as photosensitive drug eruption induced by pirfenidone. Pirfenidone was discontinued for a month, and the patient was treated with oral and topical corticosteroids. Consequently, the skin lesion almost fully cleared, leaving mild postinflammatory hyperpigmentation. Although there are many reports of photosensitivity reactions to pirfenidone, dermatologists are still not familiar with this drug.
