What type of skin change is characterized by a lace-like pattern and is seen in infants?

Cutis marmorata is a type of skin change that presents as a lace-like, mottled pattern on the skin of infants. This condition occurs due to vascular changes and is particularly common in babies, especially when they are exposed to cold temperatures. The skin appears bluish or purplish in areas, creating a marbled look. This pattern is typically more pronounced in fair-skinned infants and reflects transient vasomotor instability; it is not harmful and usually resolves with warming.

The other options describe different skin conditions. Harlequin color change is characterized by a sudden color difference between the two sides of the body in response to changes in position, which is temporary and typically not a lace-like pattern. Pustular melanosis consists of small pustules that eventually resolve, usually seen in darker-skinned infants. Neonatal rash refers to various types of skin rashes that can occur during the first weeks of life, which are unrelated to the lace-like appearance characteristic of cutis marmorata.
