Struma ovarii is a rare monodermal variant of ovarian teratoma that contains at least 50% thyroid tissue. Less than 8% of struma ovarii cases present with clinical and biochemical evidence of thyrotoxicosis due to ectopic production of thyroid hormone and only 5% undergo malignant transformation into a papillary thyroid carcinoma. Only isolated cases of hormonally active papillary thyroid carci...

Struma ovarii is a rare neoplasm that accounts for approximately 0.3% of ovarian tumors. Due to its ultrasound morphology, which is quite similar to that of malignant ovarian carcinoma, most struma ovarii cases are open operated with laparotomy rather than laparoscopy. We present 3 cases of struma ovarii, which were diagnosed preoperatively by imaging studies and removed by laparoscopic surgery...

Struma ovarii is a rare (2.7%) ovarian teratoid tumour that can be diagnosed only when thyroid tissue is the predominant element. The malignant struma ovarii is even more rare, and makes up 5% of all cases of struma ovarii. Here we report a case of malignant struma ovarii. A 76-year-old women gravida 3 and parity 3, referred to our gynecologic oncology clinic. She underwent bilateral salphingo-...

Struma ovarii belongs to the class of monodermal and highly specialized teratomas. These tumors are detected mainly among mature teratomas, accounting for up to 3% of all ovarian teratomas. Besides dermoid cysts, thyroid tissue is also found in serous and mucous cysts within the ovary. The aim of the research was to analysis of the incidence of struma ovarii – a rare type of tumor – among dermo...

Struma ovarii is an infrequent ovarian tumor, and there are only few reports with detailed data of thyroid function. In several cases, malignant struma ovarii have been shown to produce hyperthyroidism, but there is no reported case of hypothyroidism following struma ovarii tumor resection. A 62-year-old white woman underwent right ovary resection that had a pathologic diagnosis of struma ovari...

struma ovarii is an uncommon highly specialized ovarian teratoma that accounts for less than 5% of mature teratomas. it is composed predominantly of mature thyroid tissue. thyroid tissue is observed in 5%-15% of teratomas; however, to qualify as a struma ovarii tumor, the thyroid proportion must comprise more than 50% of the overall tissue. the combination of pseudo meigs'syndrome and elevation...

introduction struma ovarii is an ovarian teratoma, represented in more than 50% by thyroid tissue. five percent of struma ovarii cases have been proven to be malignant and, as in the thyroid gland, papillary thyroid carcinoma is the most common histotype arising in struma ovarii. because of the unusual occurrence of this tumor, its management and follow-up after pelvic surgery is still controve...

As clinical features in struma ovarii patients in the absence of thyrotoxicosis are generally non-specific and resemble ovarian malignancy, preoperative radiological diagnosis becomes all the more relevant in order to avoid ovarian cancer type surgery (including bilateral salpingo-oophorectomy, hysterectomy, omentectomy and occasionally appendectomy) for this usually benign and rare ovarian mas...

BACKGROUND Coexisting of Graves' disease and functioning struma ovarii is a rare condition. Although the histology of struma ovarii predominantly composed of thyrocytes, the majority of the patients did not have thyrotoxicosis. The mechanism underlying the functioning status of the tumor is still unclear but the presence of thyroid stimulating hormone receptor (TSHR) is thought to play a role. ...
