Abstract

A 40-year-old housewife visited our outpatient clinic with refractory pruritic vesicular erythematous eruptions on both hands and feet for a duration of one year. Although she had been treated with topical corticosteroid and anti-histaminics under the diagnosis of dysidrotic eczema by several dermatology clinics, her skin rash responded poorly to these regimens. We suspected plant contact dermatitis from the clinical picture and her hobby of gardening. We performed the standard patch test consisting of metals, dental materials and chemicals, all of which gave negative results. However, patch test reactions were positive to leaves of the Clematis and its water-extracted fraction. Her skin problems soon disappeared after avoiding Clematis and using topical corticosteroid. Importantly, she first denied the opportunity to have contact with Clematis, which delayed identification of the allergen causing the refractory eczema.
