A preschool-aged girl tells the school nurse that her hair hurts. The nurse finds that the child's hair has been arranged to cover several small bald spots. Which finding indicates to the nurse that the hair loss is not disease related?

A. Episodic intervals of pruritus (itching) may suggest a dermatological condition or irritation of the scalp, but they do not directly indicate that the hair loss is not disease-related. B. Erythema (redness) of the localized lesions may suggest inflammation or irritation but does not necessarily indicate that the hair loss is not disease-related. C. Ecchymotic blood accumulations (bruising) suggest trauma or repeated pulling at the hair, which is not typically associated with disease-related causes. This finding can indicate a behavioral issue, such as trichotillomania (a compulsive hair-pulling disorder), where physical damage to the scalp can result in bruising and bald patches. The presence of ecchymosis supports a mechanical, non-disease-related cause of hair loss. D. Evidence of patches of lost hair alone does not confirm whether the hair loss is disease-related or non-disease-related. Patches of hair loss can occur with both behavioral conditions (e.g., trichotillomania) and diseases (e.g., alopecia areata, fungal infections).
