What common pediatric condition is referred to as "cradle cap"?

"Cradle cap" is a term commonly used to describe seborrheic dermatitis, particularly in infants. This condition is characterized by thick, yellowish, greasy scales on the scalp, which can sometimes extend to other areas of the body, such as the face and behind the ears. The exact cause of cradle cap is not fully understood, but it is believed to be associated with an overproduction of oil by sebaceous glands and possibly linked to yeast (Malassezia) that thrives in oily environments.

In infants, cradle cap usually disappears on its own within a few months, but gentle washing with mild shampoo and the use of soft brushes can help manage the flakes. While other skin conditions like contact dermatitis, atopic dermatitis, and psoriasis can occur in children, they have distinct presentations and etiologies that do not align with the typical features of cradle cap. For instance, contact dermatitis is often associated with specific allergens or irritants, atopic dermatitis is characterized by dry, itchy skin and sometimes associated with food allergies, and psoriasis presents with well-defined, red, scaly patches that can be itchy and painful. Understanding these distinctions helps clearly identify seborrheic dermatitis as the correct match for the term "cradle cap."
