Adolescent Polycystic Ovary Syndrome: An Update.

Menstrual irregularities and cutaneous signs of androgen excess are commonly encountered when caring for adolescent girls. Polycystic ovary syndrome (PCOS) is the most common cause of these symptoms in adult women, and it can be diagnosed in adolescents as well. Diagnostic criteria used to diagnose adult women are not applicable in adolescents, as some diagnostic criteria overlap with the normal physiology of a maturing reproductive system. Thus, application of adult criteria will overdiagnose adolescents with PCOS. Two recent guidelines on the diagnosis and treatment of PCOS in adolescence were created to provide clarity in the diagnosis of PCOS in adolescent girls and to guide best practices in treatment. This review summarizes the recommendations and gives practical advice on the application of these recommendations to everyday pediatric practice. [Pediatr Ann. 2019;48(8):e304-e310.].
