Research output: Contribution to journalArticlepeer-review


Congenital skin dimples (SD) are small cutaneous depressions that can be noted on any part of the body and may be caused by traumatic, mechanical, metabolic, and genetic factors as well as by exposure to infections or drugs. We describe 3 cases of unrelated healthy newborns displaying SD and discuss as a possible explanation the persistent friction of the big toenail onto the immature skin of the fetus during intrauterine life causing as depression in the skin.
