Symmetrical erosions in a neonate: a case of neonatal sucking blisters.

Neonatal sucking blisters appears as unilateral or bilaterally symmetrical bullae or erosions involving the distal upper extremities at birth. They represent minor self-inflicted trauma, presumably the result of a vigorous intrauterine sucking reflex. Recognizing this benign self-limited condition avoids unnecessary tests and alleviates anxiety on the part of the infant's family and physicians.
