Background: In the current situation, where severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) is rapidly spreading, vaccines for coronavirus are thought to be the most effective approach to containing the situation. However, limited comparative data are available on cutaneous adverse reactions to coronavirus vaccination in Korea. Objective: We retrospectively reviewed the clinical and histopathological characteristics of adverse cutaneous reactions following coronavirus vaccination. Methods: We retrospectively reviewed the clinical and histopathological characteristics of 95 patients who were vaccinated with Pfizer, Moderna, AstraZeneca, and Janssen vaccines and visited the Dermatology Departments of Dankook University Hospital and Chungnam National University Hospital. Results: The mean age was 49.3±17.5 years. Patients who received the AstraZeneca vaccine had an average age of 61.7±10.8 years, significantly higher than those in the Pfizer (44.1±18.7 years) and Moderna (42.5±15.0 years) groups (p＜0.001). Of the 95 patients, 36 (37.9%) were diagnosed with urticaria, 24 (25.3%) with morbilliform eruption, 18 (18.9%) with petechiae and purpura, and eight (8.4%) with erythema multiforme. Additionally, there were diagnoses of erythema nodosum, alopecia areata, eczema, generalized pustular psoriasis, acute generalized exanthematous pustulosis, pityriasis rosea, and bullous pemphigoid. In the AstraZeneca-vaccinated group, the proportion of morbilliform eruptions was significantly higher than that in the Pfizer- and Moderna-vaccinated groups (p=0.008). The Pfizer- and Moderna-vaccinated groups had higher rates of urticaria than did the AstraZeneca-vaccinated group. However, this difference was not statistically significant (p=0.083). Conclusion: This study described the clinical characteristics of cutaneous adverse reactions after coronavirus vaccination. (Korean J Dermatol 2024;62(2):69∼76)
