Objective: To evaluate clinical and pathological features of struma ovarii cases retrospectively. Materials-Metods: The present study included 8 patients reported with pathology of struma ovarii in the medical records. Archive slides were reviewed for diagnostic confirmation, regarding patterns and accompanying thyroid pathologies. Extraovarian dissemination of thyroid tissue, presence of accompanying other ovarian pathologies and that how many cases were composed of pure thyroid tissues were investigated. The clinical features were determined by screening the patient files. Data such tumor size and lateralization were obtained from the pathology reports. Results: The age of the patients ranged between 45-85 years. The most common hospital admission complaint was palpable mass. Five patients had right ovarian struma ovarii. The tumor diamater ranged between 9-15 cm. Tumor was limited by ovary in all the cases. All the struma ovarii cases demonstrated follicular pattern in the microscopic examination. No thyroid-associated malignancy was encountered. Tumor was composed of pure thyroid tissue in 6 cases. We assessed two cases as proliferative struma ovarii. Recurrence was detected during follow-ups in none of the cases. Coclusion: Struma ovarii is the most commonly seen ovarian monodermal teratoma and mostly benign. The presence of malignancy associated with thyroid should be eliminated by a careful histopathological examination in order not to hinder the chance of additional treatment.
