[Struma ovarii. Analysis of a series of 7 cases and review of the literature].

The authors report the result of a retrospective study of 7 cases of struma ovarii, four malignant and three benign cases, removed surgically at the Salah Azaiez Institute, Tunis, Tunisia, over a period of 20 years (1980-2000). Based on their personal experience and on a review of the literature, the authors discuss the diagnosis, management and outcome of struma ovarii, in particular with malignant transformation. Echography objectives pelvic tumor in all cases. The diagnosis is usually histological. Treatment is exclusively surgically, all patients with malignant struma ovarii were staged la (FIGO). Mean follow up was 4 years and 4 months (range: 1-7 years). No recurrences were reported and no distant metastases. Supervision was based on serum level thyroglobuline and scintigraphy with iodine 131. Histologic diagnosis of malignancy is difficult. Treatment is based on surgery and prognosis is relatively favorable even in malignant cases.
