Premature Pubarche: A Pragmatic Approach

Premature pubarche (PP) is a common and usually benign variant of normal puberty most often seen in 5-year-old to 9-year-old children. Some providers routinely order laboratory testing and a bone age to try to rule out other diagnoses including nonclassic congenital adrenal hyperplasia and gonadal or adrenal tumors. I review the natural history of PP and studies which suggest that without clinical features such as rapid growth and progression or genital enlargement, it is unlikely that a treatable condition will be found. Therefore it is recommended that patients with PP not undergo testing unless there are red flags at the time of the initial visit.
