Two patients presented with cheilitis and perioral dermatitis. Patch testing revealed positive reactions to both Myroxylon pereirae (MP; formerly known as Balsam of Peru) and Lucas Papaw Ointment (LPO; Lucas Papaw Remedies, Bisbane, Qld, Australia). MP was not listed as an ingredient in LPO, however the manufacturer confirmed that a small amount of MP was present in LPO and we believe this to be the cause of the patients' dermatitis.
