A 9-month-old girl presented for a well-child check. She was in the 75th percentile for weight and 50th percentile for length. She had excessive skin folds over her arms and legs and bilateral epicanthic folds. She was developmentally appropriate and had no other congenital anomalies. The rest of the physical examination findings were normal.
What are these circumferential symmetric skin creases called? Does this finding portend a benign or ominous prognosis?
