RESUMO
CASE REPORT: A 35-yr-old patient suffering from secondary amenorrhea for two years before she was diagnosed. Secondary amenorrhea occurred after the first normal vaginal delivery, and it was initially associated with breastfeeding and a formerly diagnosed thyroid disease. Transvaginal ultrasound confirmed a tumorous mass of the right ovary. Blood hormone tests detected high serum inhibin B and Anti-Müllerian hormone levels and high androgen level with no signs of virilization. Surgical treatment was indicated for a definitive diagnosis of suspected sex cord-stromal tumor. Right-sided laparoscopic salpingo-oophorectomy was performed, and the histopathological analysis confirmed the diagnosis of granulosa cell tumor adult type. The oncological team recommended adjuvant chemotherapy after the operation, but the patient did not give an informed consent. One month after surgical treatment, spontaneous menstrual bleeding occurred with normalization of sex hormone levels and the menstrual cycle. Nine months after surgical treatment, the patient was examined again due to secondary amenorrhea. Ultrasound confirmed a vital intrauterine pregnancy. The pregnancy course was normal, and the patient had a full-term spontaneous vaginal delivery of her second child. CONCLUSION: Restoration of fertility after a temporary loss due to hormone-secreting granulosa cell tumor is possible after sparing surgical treatment. The role of adjuvant chemotherapy is controversial, particularly in patients with stage I-II disease because of the rarity of this tumor and the absence of prospective randomized studies.
