Counsel parents of a tall child referred for overgrowth assessment — OSCE

Candidate brief

You have eight minutes to counsel the parents of a seven-year-old boy referred for tall stature and a possible overgrowth syndrome, navigating the tension between reassurance and appropriate investigation. Use a structured, honest, empathic approach that acknowledges the parents' anxiety, builds a shared assessment plan, and explains the next steps in plain language. [6] [8]

Key teaching and communication objectives

Acknowledge and validate the parents' anxiety before delivering information, and allow space for their fear. Explain that tall stature is common and that the great majority of tall children are healthy — particularly when, as here, both parents are tall — but that the referral is appropriate because a small number of tall children carry a condition that benefits from early recognition. Frame the assessment as a structured check that will either confirm the reassuring explanation or identify something to manage, and emphasise that the aim is to be thorough, not to alarm. [6]

Explain in plain language what the assessment involves: plotting the growth carefully and measuring the growth velocity, examining the body proportions and the face, looking at the development and the learning, and taking a bone-age X-ray. Address the facial features honestly — the prominent forehead and the long face may be a family trait, or they may be a sign that earns a genetic test — and explain that the decision to test rests on combining all the pieces rather than on any single feature. Name that a genetic test, if needed, is a blood test that looks at specific genes, and that it is ordered only when the assessment points toward a specific condition. [8]

Address the cancer-risk fear directly and without minimising it. Explain that the tumour risk that some overgrowth syndromes carry is real but is specific to particular conditions — particularly the overgrowth that comes with asymmetry in infancy — and that the boy's pattern does not match that fingerprint. Reassure the parents that the assessment is designed to identify the children who do need tumour surveillance, and that if the assessment confirms a familial explanation, no surveillance is needed. [9]

Close with a shared plan and a clear next appointment: complete the growth assessment, the examination, and the bone age; review the results together; and decide together whether a genetic test is warranted. Offer a connection to a support organisation if a diagnosis is made, and an open invitation to return with questions. Name the coordinator who will hold the plan, and frame the conversation around the boy as a person — bright, socially finding his way, and growing — rather than around a syndrome. [1] [6]
