Introduction Granulosa cell tumors (GCTs) are rare functional sex-cord-stromal ovarian neoplasms characterized by low malignancy potential and late relapse, which rarely metastasize to the liver. Presentation of case A 43-year-old female, who had undergone surgery to treat a GCT of the left ovary in 1976, complained of abdominal distention in May 2001. Imaging studies demonstrated masses in the right lobe of the liver, together with massive ascites. The patient's bloody ascites showed no cytological evidence of malignancy. A diagnostic laparoscopy was performed, and the biopsy specimen was histologically proven to be a recurrent granulosa cell tumor. The patient was successfully treated surgery followed by systemic chemotherapy. Her postoperative course was uneventful and systemic chemotherapy was repeated due to the suspicion of a recurrence in the pelvic cavity. Discussion GCTs which are rare malignant tumors of the ovary, tend to be associated with late recurrence. Although most recurrences occur within 10 years after the initial diagnosis, there are occasional reports of recurrences after 10 years have been. We experienced the rare case of a patient who relapsed 25 years after the initial diagnosis. Conclusion The long natural history of this disease highlights the importance of extended follow up for GCT patients. In addition, aggressive therapy including surgery and chemotherapy may contribute to a patient's long-term prognosis.
