Severe contact dermatitis as a result of an antiseptic bath oil

Siblings aged 7 and 5 years developed extensive truncal and flexural inflammation and desquamation unresponsive to standard eczema therapy. After delays in diagnosis, subsequent history revealed prior use of an antiseptic bath oil in a much stronger concentration than recommended. The case illustrates the severe irritant contact dermatitis that can arise following inadequate dilution of antiseptic bath oils, presumably as a result of skin contact with benzalkonium chloride and triclosan. Features that may direct attention to such irritant dermatitis are flexural predominance with superficial desquamation and rapid improvement after avoidance of exposure to the antiseptic solution.
