Abstract

Background: McCune–Albright syndrome (MAS) is a rare sporadic disorder commonly associated with peripheral precocious puberty (PPP) in girls due to autonomous ovarian estrogen production. PPP often presents early, progresses unpredictably, and poses significant challenges to growth preservation and pubertal control. 


Case summary: This is a report of the long-term growth and pubertal outcomes of an eight-year medical treatment course in a girl who presented at 15 months of age with breast and pubic hair development and cyclical vaginal bleeding. She had café-au-lait macules, markedly elevated estradiol levels with suppressed gonadotropins, advanced bone age, and pelvic ultrasonographic findings consistent with estrogen exposure, confirming PPP in the setting of MAS. Treatment with the aromatase inhibitor, anastrozole led to marked reduction in vaginal bleeding frequency and eventual cessation, stabilization of pubertal progression, and moderated bone age advancement. Anastrozole was discontinued after seven years of therapy when she was 8 years and nine months. Menarche occurred within two weeks of stoppage of therapy, and regular menstrual cycles ensued. By 16 years of age, the patient attained a near-final height of 153 cm, close to her mid-parental target height. 


Conclusion: This case highlights the effectiveness of prolonged aromatase inhibitor therapy and sustained follow-up in optimizing growth and pubertal outcomes in MAS-associated PPP, particularly in resource-limited settings.
