xerosis

Full Definition

Xerosis refers to abnormal dryness of the skin characterized by rough, scaly, and sometimes fissured appearance. In pediatric patients, it is often associated with atopic dermatitis, low humidity environments, excessive bathing with hot water, or genetic conditions affecting skin barrier function. The condition is particularly common during winter months and in children with a predisposition to eczema. Management focuses on restoring and maintaining skin hydration through appropriate moisturizing regimens.

Usage

Usage note: More precise than 'dry skin' in medical documentation; avoid confusion with xerostomia (dry mouth).
