To the Editor: An 18-month-old girl was noted by her babysitter to have extensive “cold sores” on her lips. Two days earlier the child had been shopping with her father, who purchased her first French vanilla ice-cream cone. She ate the ice cream enthusiastically for 30 minutes, never removing her mouth from the delightful treat. When the child returned home, her mother noted swollen, dusky, and warm upper and lower lips. Over the next 24 to 48 hours the affected areas progressed in a manner typical of a local frostbite, with blistering occurring on both the upper and lower.
