BACKGROUND: Meigs syndrome is rare in women under 30 years of age and even more if associated with an elevated CA-125. In this case, malignancy was suspected and raised concerns about fertility preservation.CASE: A 13-year-old girl presented with a 4-month amenorrhea, abdominal enlargement and dyspnea. Ultrasonography showed a 14-cm solid mass with ascites, bilateral pleural effusion and, analytically, elevated serum CA-125. Unilateral salpingo-oophorectomy was performed, with a 19 ? 15 ? 12 cm mass being disclosed from the right ovary. Final pathology diagnosed a mitotically active cellular ovarian fibroma (MACF), with no significant nuclear atypia.CONCLUSION: MACF is a recent histopathologic entity. Despite the high count of mitotic figures, it is not associated with atypia, which contributes to favorable outcome. Although initial suspicions of malignancy, a conservative surgical intervention allowed fertility preservation. This was clinically appropriate and with no implications on survival and prognosis of these patients.
