BACKGROUND: Antimüllerian hormone is a marker of ovarian reserve and is now routinely measured in women seeking infertility treatment. CASE: A 42-year-old woman, gravida 1, abortus 1, presented with secondary infertility. Obtained originally for assessment of ovarian reserve, an antimüllerian hormone of more than 160 ng/mL raised suspicion for a granulosa cell tumor. A laparoscopic right salpingo-oophorectomy, pelvic washings, dilation and curettage, and peritoneal and omental biopsies were performed. A well-differentiated granulosa cell tumor confined to the right ovary was consistent with stage 1A disease. CONCLUSION: As the use of antimüllerian hormone becomes more common for ovarian reserve testing, providers need to maintain an awareness for neoplastic disease with abnormal values.
