Clinical Features of Chilblain in Korean Soldiers / 대한피부과학회지

ABSTRACT

BACKGROUND: Chilblain or pernio is a cold-induced, inflammatory skin problem which occurs usually on acral areas bilaterally. Because chilblain commonly develops in cold, damp climates, many soldiers may experience occupational chilblain during military service in Korea. OBJECTIVE: The purpose of this study is to analyze the clinical characteristics of chilblain in Korean soldiers. METHODS: We reviewed the clinical findings in 199 patients with chilblain who visited the department of dermatology, Armed Forces Capital Hospital during the 5-year period from 2002 to 2007. We investigated the epidemiology, aggravation factors, duration of the disease, clinical manifestations and treatment. RESULTS: The results were as follows; The average age was 21.51+/-1.86 years old. The chilblain usually developed during winter and the duration of symptoms ranged from 1 day to 4 years. All patients developed skin lesions on acral areas. Erythematous skin lesions were observed in 133 patients and purpuric lesions were seen in 56 patients. The lesions were symmetrical in 171 patients 43 patients had history of recurrence. Treatment includes nifedipine and pentoxyfilline. The supportive treatment includes rest and keeping warm, topical corticosteroids or antibiotics and oral antihistamine, analgesics, or antibiotics. CONCLUSION: This investigation is expected to help understand and obtain more information on chilblain.
