38. Clinical features and associated factors of nummular eczema disorder
Main Article Content
Abstract
A cross-sectional descriptive study was conducted on 120 patients with nummular eczema at the National Hospital of Dermatology and Venereology from November 2024 to May 2025 to describe clinical characteristics and related factors. The results showed that the median age was 18 years old (IQR 10 - 31.3 years old), the median age of the onset was 17 years old (IQR 9 - 28 years old) with a male-to-female ratio of 58/62. The majority of patients resided in rural areas (63.3%). A previous history of nummular eczema was noted in 56.7% of patients, with a high recurrence rate. The disease most commonly began in winter (73.3%). Common lesions included erythematous patches (100%), papules/vesicular papules (82.5%), oozing (24.2%), crusts (81.7%). The most frequently affected sites were the lower limbs (73.3%) and upper limbs (46.7%), with symmetrical distribution observed in 54.2% of cases. Most patients (78.3%) had moderate lesion severity, accompanied by moderate (55.2%) to severe (39.1%) pruritus. Contributing factors included scratching (90.8%), bathing with hot water (54.2%), xerosis and long fingernails (50%), personal history of atopic allergy (40%), bathing with herbal leaves (20.8%), and skin trauma (17.5%). The mild disease group and the moderate/severe disease group only differed in lesion areas and itching level, with no difference in other factors.
