Congenital double lower lip in a newborn with feeding difficulties
Abstract
We describe the case of a full-term male newborn admitted on the first day of life due to feeding difficulties and hypoglycemia, who presented with a protruding bifid mass along the mucosa of the lower lip that interfered with breastfeeding. Double lip is a rare congenital condition caused by hyperplasia of the lip mucosa, most commonly affecting the upper lip. Surgical removal is generally recommended if the condition interferes with speech, sucking, or, more commonly, for cosmetic reasons. In this case treatment was conservative, resolving feeding difficulties without the need for surgery, with adequate weight gain and no further breastfeeding difficulties at follow-up visits up to 3 months of age, when follow-up was lost.
