We describe a 3-month-old child with an infantile hemangioma on the forehead with a blanched macule provoked by topical treatment with propranolol. This observation demonstrates that topically applied (non-selective) beta-blockers may induce blanched macules at the site of application, a side effect due to peripheral vasoconstriction of blood vessels by non-selective beta-2 blockade. This side effect was linked due to overuse and was reversible. This case illustrates the importance of providing thorough instructions regarding topical propranolol application.
