Transient alterations in pigmentation are frequently observed in black neon
ates, but to our knowledge, have not previously been reported in Caucasian
infants. In 54 Caucasian newborns, we found at least mild periungual hyperp
igmentation similar to the variation in coloration in the periungual region
of many black newborns. This pigmentation should be added to the transient
benign dermatoses of Caucasian infants.
