A full-term female infant was born via spontaneous vaginal delivery to a 30-year-old primigravida after an uncomplicated pregnancy. Physical examination results of the newborn following delivery revealed linear bullae on the dorsal aspect of all fingers and thumb on her left hand (Figure) and a single blister on the left forearm. All bullae were filled with clear fluid. The remainder of the physical examination, including the rest of the skin and mucosae, was unremarkable. There was no maternal history of infections, immunobullous disorders, or autoimmune diseases and no family history of hereditary bullous disorders. The child was breastfed and was observed to be sucking on the lesions. The bullae resolved spontaneously and healed without scarring by 8 days of life. No skin fragility, new blisters, or erosions were noted after resolution.
