Central precocious puberty: A case report

Abstract

Precocious puberty is the onset of physical and hormonal signs of pubertal development before the age of 9 years in males and 8 years in females. A 2-year 9-month-old Indian male child was brought to the hospital with complaints of excessive growth of pubic hair and increase in penile length for 2 months. On local examination of the genitalia, pubic hair was ++, his penile length was 9 cm, and testicular volume was >4 mL. The Sexual Maturity Rating score was A1P2T4. Serum testosterone levels – 592.76 mmol/L; serum luteinizing hormone – 2.18 IU/L; and serum follicle-stimulating hormone – 4.69 IU/L. His X-ray of the left wrist showed bone age >6 years. Magnetic resonance imaging of the brain showed an ill-defined, T2-hyperintense mass involving the right half of the tuber cinereum. A diagnosis of central precocious puberty due hypothalamic hamartoma was made. During the course of his admission, he was given injection leuprodex 3.75 mg intramuscularly once in 28 days. He was discharged with a plan to follow-up on outpatient basis.
