Introduction: Polycystic ovary syndrome (PCOS) is a common endocrine system disorder among women of reproductive age. Although some studies have suggested an association between PCOS and autoimmune thyroiditis, only a few cases indicating association between PCOS and Graves disease are reported.
Case report: We present a woman aged 29 with Graves' disease certified by suppressed TSH (0.001 mUI/l), high FT4 (6.6 ng/dl) associated with elevated TRAb (32 IU/l) and elevated TPOAb (476 IU/l). BMI was 21.33 kg/m2, menarche at 12.6 years, oligomenorrhea for about 1 year, waist circumference 76 cm, Ferriman - Gallwey score was 15. Total testosterone was 77.02 ng/dl (25.065), LH and FSH was 19 IU/l (219) and 7.33 IU/l (4.59.31) respectively with LH/FSH ratio 2.59. Prolactin and 17-hydroxyprogesterone was in the normal range. The transabdominal USG was suggestive for PCOS by presence of 1011 peripheral follicles each 27 mm in diameter in both ovaries.
Conclusions: The association of a Graves disease with PCOS is unlikely to be because of a chance alone and may point to a common aetiopathogenic linkage.
