[Hypothyroidism in the developing stage of the woman with comorbid polycystic ovary.].

Polycystic ovary syndrome (Pcos) and thyroid disorders, particularly Hashimoto's Thyroiditis (HT), are very common conditions in young women. Some studies have suggested a possible association between Pcos and thyroid disorders, postulating common pathogenic mechanisms. In fact, a higher prevalence of HT and hypothyroidism has been reported in women with Pcos, and vice versa. Both Pcos and thyroid disorders can potentially compromise metabolic profiles, and the coexistence of these two conditions may worsen it in an additive manner. We present the case of a young woman with a classic Pcos phenotype and HT with manifest hypothyroidism, complicated by altered metabolic status despite her young age.
