Neonatal sucking blister


Neonatal sucking blisters result from vigorous sucking on hand or forearm in utero. Clinically, one observes a tense, fluid-filled blister, which when ruptured forms an erosion. We report a female neonate with a sucking blister on the distal dorsal aspect of her left forearm. These benign bullae should be differentiated from other diseases of the newborn through their presentation, characteristic morphology, and self-limiting course.
