The ultrasound performed showed multiple right ovarian cystic ranging from 0.4 to 4 cm on the long axis. She underwent a right salpingo-oophorectomy in May 2022. The anatomical pathology result is in favor of a papillary carcinoma developed on stroma ovarii. No adjuvant treatment was necessary since the tumor was well limited, without capsular rupture, stage IA. The thyroid test was normal. The patient is currently being monitored. There is no sign of recurrence 20 months after surgery.展开更多

Malignant transformation may occur in rare cases. Papillary thyroid-type carcinoma represents the most common type of malignant struma ovarii, followed by follicular carcinoma. Malignant struma ovarii is commonly seen in women in the fifth decade. The diagnosis is often made post-operatively after histological examination. Histology also helps assess tumor aggressiveness (mitoses, necrosis, poorly differentiated subtype, etc.). Given the rarity of these lesions, no therapeutic consensus or prognostic value had yet been formally established. We report herein, the case of a 76-year-old woman with a cystic tumor of the right ovary and a nodular lesion of the bladder. The clinical symptomatology is nonspecific, associating abdomino-pelvic pain and a right latero-uterine mass on abdominal palpation. After total hysterectomy with bilateral adnexectomy, the diagnosis of papillary carcinoma arising from struma ovarii and extending into the bladder was made. Through this observation, we suggest to discuss the anatomoclinical particularities of this rare pathological entity.展开更多

The patient was a 34-year-old Japanese woman, gravida 1, para 1, who had the left adnexal mass, and was pre-operatively diagnosed as left ovarian endometriotic cyst or mature cystic teratoma by magnetic resonance imaging findings. She underwent laparoscopy, and the content of the left ovarian cystic tumor was found to be yellow gelatinous material, suggesting mature cystic teratoma. The imprint cytology of the tumor showed benign glandular pattern, suggesting struma ovarii. Histopathological findings led us to the diagnosis of pure struma ovarii with positive reactions for thyroglobulin and thyroid transcription factor-1. No metastases or disseminated lesions were detected. The patient has no recurrent signs 7 months after the operation.展开更多

The preoperative diagnosis is always difficult to identify without histopathological examination. Surgery is the only treatment because malignant alteration is possible and thyroid hyperactivity or hyperthyroidism may occur. Our patient, a post-menopausal women, had unilateral, large, multiloculated ovary mass of 20 cmx 15 cm × 10 cm size without any thyroid hyper activity. The radical excision of the tumor with right ovary was preformed. Histopathological examination confirmed struma ovarii. The post-operative period was uneventful and her thyroid function remained normal.展开更多

An intraoperative diagnosis of benign struma ovarii enables the general gynecologic surgeon to continue the planned surgery. However, a diagnosis of malignnancy in a struma ovarii would alter the course of surgery with the involvement of a gynecologic oncology surgeon. We present here that our experience with intraoperative consultation for preoperatively undiagnosed struma ovarii presenting as an adnexal cystic or solid mass at our teaching hospital. Fifty-three cases of struma ovarii, 5.2% of all cystic teratoma of the same period, were diagnosed between January 1991 and March 2011. All intraoperative consultation reports, gross descriptions and final pathology reports were reviewed. The H&E stained slides and in selected cases, immunohistochemistry stained slides, were reviewed. Of the 53 cases of struma ovarii, intraoperative consultation was requested on 48 cases. Frozen section was done on 24 cases and only gross examination was felt appropriate in remaining 24 cases. 83% cases were diagnosed when a frozen section was done. None of the remaining 24 cases were recognized as struma by gross inspection. Our findings reveal that in a large number of cases the diagnosis of struma ovarii remained unrecognized during intraoperative consultation, indicating its often subtle/deceptive gross morphologic appearance. However, the purpose of the intraoperative consultation was served, as appropriate information was provided to the surgeon to guide the surgical management.展开更多

Methods:Fifty-three cases of struma ovarii treated in this hospital from January 1988 to January 2008 were analyzed retrospectively,and related literatures were reviewed. Results:Struma ovarii accounted for 1.5%of ovarian teratomas diagnosed at the studied period.The mean age of onset was 39.5 years.All cases were unilateral,occurring equally in either side,with a normal contralateral ovary. Elevated serum levels of CA125(50-2265.7 U/ml) were observed in all 5 patients with ascites.There were no characteristic imaging findings and the confirmed diagnosis was dependent on histology.The management for all patients was surgery.No reoccurrence was found within mean follow-up of 58 months after operation. Conclusion:Struma ovarii is rare and occurs more often in late reproductive age,with a good prognosis.It is difficult to be diagnosed before surgery,and should be distinguished from malignant ovarian tumor.Laparoscopy is the best choice of treatment.展开更多
