Abstract
An ornamental succulent plant sold in many plant stores in the Chicago [Illinois, USA] area was identified as E. hermentiana Lem. Open and closed patch testing using undiluted latex from this species was performed on 5 Caucasian volunteers. Open testing on flexor forearms resulted in irritant follicular dermatitis, while closed testing to the flexor surfaces of both upper arms in each subject produced bullae and vesiculation with residual desquamation and hyperpigmentation. Dermatological signs persisted for over a week following latex application.
