Mitten-line hyperpigmentation: a reactive process analogous to sock-line hyperpigmentation

Pediatr Dermatol. 2010 Jul-Aug;27(4):401-2. doi: 10.1111/j.1525-1470.2010.01180.x.


A 3-month-old girl presented with a 6-week history of a curvilinear hyperpigmented patch on the left wrist, which began within a day of using a tight mitten. Mitten-line hyperpigmentation is analogous to the recently described condition known as infantile "sock-line hyperpigmentation," or more generally "sock-line bands." Distinguishing this benign condition from child abuse, amniotic band syndrome, and acquired raised bands of infancy is important but sometimes challenging.
