A four-year-old boy had a split in a crease in his lower lip that had not healed for more than six weeks. There were no signs of bacterial infection; application of bacitracin/neomycin/polymyxin B (Neosporin) cream had no effect. Every time the boy smiled, the split would open and bleed again. It finally healed with a three-day course of nystatin/triamcinolone (Mycolog-II) t.i.d. Why was this split so slow to heal? Are there other topical agents you would have recommended?

It is important to determine if there was any recurrent trauma or lip-licking. I would recommend conservative therapy, with a topical antibiotic and zinc oxide ointment. In the case of overt inflammation, a topical corticosteroid or calcineurin inhibitor, such as pimecrolimus cream, might be helpful.
