Abstract
A 16-year-old girl was admitted to the hospital for the absence of a menstrual bleeding over 10 mounts. She has had regular menstrual periods since she was 13 years old and no history of systemic disease. Laboratory tests showed low estrogen (<11.8 ng/L, range 16–238 ng/L), elevated FSH (follicle stimulating hormone) (138.3 U/L), low AMH (anti-Mullerian hormone) (<0.01 µg/L), normal prolactin (7 μg/L), and thyroid hormone levels (TSH: 1.5 mU/L). The ovaries were prepubertal in size and diagnosed with primer ovarian failure. ANA titers, antiphospholipid antibody, and direct coombs were positive. Microscopic hematuria and nephritic proteinuria (34 mg/m2/hour) were also detected and renal biopsy was revealed stage 3–5 lupus nephritis. Premature ovarian failure is an extremely rare disease in childhood. When POF is detected in the adolescent, it is important to investigate the etiology. In this way, it may be possible to diagnose diseases with high morbidity and mortality that may cause POF.
