Abstract
A 10-year-old girl developed itchy erythema on her cheek. She had no symptoms of collagen disease, and no history of taking any medicine. Since it was regarded as a contact dermatitis to something encountered in her environment, patch tests to some plants were performed. A patch test with a water extract of the leaves of Podocarpus macrophyllus var. chinensis (Roxb.) Maxim showed a positive reaction at D2(++) and D3(++). Patch tests with extracts of three other grasses were negative. A diagnosis of contact dermatitis to Podocarpus macrophyllus var. chinensis (Roxb.) Maxim was thus made. To the best of our knowledge, this is the first report of allergic contact dermatitis caused by Podocarpus macrophyllus var. chinensis (Roxb.) Maxim, although contact dermatitis to other Podocarpus species has been reported.
