During a well-child visit, a child presents with yellow serpentine-border lesions on the tongue. What is the best course of action?

• A. Order chlorhexidine gluconate rinses to treat the lesions
• B. Prescribe oral acyclovir to shorten the course
• C. Reassure the parent that these are benign lesions
• D. Refer the child to a pediatric dentist for evaluation

Answer: (C)

Geographic tongue is a common, harmless variation of the tongue’s surface. It presents as irregular, map-like red patches with yellowish serpentine borders that can migrate over time. In a well child, these lesions are typically asymptomatic and require no treatment. Reassurance is the best course because these spots will often move or fade on their own and do not indicate infection or systemic illness. Chlorhexidine rinses target bacterial or fungal issues and aren’t indicated for this condition. Oral acyclovir would be used for viral infections such as herpes, which present differently (painful ulcers, vesicles, possible fever). Referring to a pediatric dentist isn’t necessary unless there are unusual features or persistent symptoms beyond typical variants, which isn’t the case here.
