Question

A child is 9 years and 3 months old, with a small, coin-sized hard lump felt in the breast, which is painful upon touch and has been present for about 10 days. Is it precocious puberty? No examination has been done yet; what tests should be done?

Answer

Precocious puberty refers to secondary sexual development abnormalities in girls before the age of 8. According to the pathogenesis and clinical manifestations, it is divided into central precocious puberty and peripheral precocious puberty. The examinations include bone age examination, ultrasound examination, sex hormone examination, and GnRH or similar stimulation tests. Therefore, it is recommended to undergo the relevant examinations as soon as possible to confirm the diagnosis.
