A case study published online October 14, 2026, in the Journal of the American Academy of Dermatology confronts a dilemma pediatric dermatologists know well: what to do when parents request a biopsy that a child's clinical picture doesn't call for.

The article, authored by Makenna C. Chapman, Kalyani S. Marathe and Christina N. Kraus, takes on pediatric vulvar lichen sclerosus. It is a condition where the diagnosis often rests on clinical grounds alone, and where an anogenital biopsy in a child carries burdens that reach well beyond the procedure itself.

The setting is familiar to anyone who treats children. A parent, worried by what they've read online or frightened by the appearance of symptoms, asks for definitive tissue confirmation. The clinician must weigh that request against the child's comfort, the modest diagnostic yield, and the ethics of performing an invasive procedure on an anogenital site in a minor.

Why does the question matter?

Vulvar lichen sclerorus in pediatric patients typically announces itself clinically. When the presentation is characteristic, guidelines generally support diagnosis without biopsy. That leaves the clinician navigating between two obligations: honoring parental concern and avoiding an unnecessary, potentially distressing intervention on a sensitive site.

The authors frame the tension precisely. The child cannot consent in the legal sense. The parents can authorize, but their authorization doesn't automatically make the procedure clinically indicated. Somewhere in that gap, the dermatologist has to make a defensible call and document the reasoning behind it.

What ethical principles are in play?

The case turns on a handful of established frameworks:

• Best interest of the child — the primary standard for pediatric decision-making
• Assent and dissent — acknowledging the child's own voice, especially in procedures involving sensitive anatomy
• Proportionality — matching invasiveness of intervention to diagnostic necessity
• Shared decision-making — engaging parents as partners rather than order-takers or obstacles

Chapman and colleagues walk through how these principles apply when a family's request and clinical judgment diverge. The anogenital context sharpens every consideration: the potential for physical discomfort, psychological impact, and the child's future relationship with medical care.

What should clinicians actually do?

The authors argue for communication first. Explaining the clinical basis for diagnosis, the limits of histopathology in lichen sclerosus, and the burdens of biopsy gives parents the tools to understand why watchful management may serve their child better than a procedure.

When the presentation is atypical or malignancy is a genuine concern, the calculus changes — and biopsy becomes defensible. The skill lies in distinguishing parental anxiety from clinical uncertainty, and in documenting that distinction clearly.

The takeaway, in plain words: a parental request is a conversation to have, not an order to fill. As pediatric dermatology continues to formalize its approach to adolescent and genital skin disease, cases like this one give clinicians a template for saying no — carefully, ethically and with the child at the center.
