A mother concerned about the appearance of persistent yellow, greasy plaques on the head of her three-month-old baby. The child was completely unperturbed, with no itching or scratching in the area, and there were no other signs or rashes on other parts of the body. The mother had first noticed the plaques when the baby was about three weeks old, but they had become progressively more obvious.
