Malignant struma ovarii (MSO) is a very rare, germ cell tumor of the ovary, histologically identical to differentiated thyroid cancers. Struma ovarii (SO) is difficult to diagnose on clinical basis or imaging and is mostly discovered incidentally, with few published cases in the
OBJECTIVE
To study the clinical features, treatment and prognosis of struma ovarii.
METHODS
From January 1990 to January 2012, a total of 68 patients were diagnosed struma ovarii at the Department of Obstetrics and Gynecology, Peking Union Medical College Hospital. Clinical data of these patients
Malignant transformation of benign monodermal teratoma is a rare presentation of struma ovarii. A 41-year-old Filipina presented with 1-year history of recurrent lower abdominal pain, abdominal swelling and vomiting. Ultrasound of the abdomen revealed a large cystic abdomino-pelvic mass densely
Brenner tumor and struma ovarii, two uncommon ovarian tumors arising alone or together with dermoid cysts or adenomas, are both rare entities. Both tumors rarely become malignant and rarely metastasize. Few published reports describe coexisting Brenner tumor and malignant struma ovarii. Patients in
BACKGROUND
Struma ovarii (SO) is a rare form of ovarian mature teratoma in which thyroid tissue is the predominant element. Because of its rarity, the differential diagnosis between benign and malignant SO has not been clearly defined. It is believed that malignant transformation of SO has similar
Inside the germinal neoplasms of the ovary, the monodermic or specializad teratomas constitute a not very frequent variety. The struma ovarii represents 2.7% as the form more common of this teratomas type, constituted by thyroid tissue. Struma ovarii can associate to other tumors of the ovary of
Struma ovarii is an uncommon type of ovarian tumor derived by germinal cells, characterized by the predominance of thyroid tissue (> 50%); 90-95% of these formations are benign and mainly affect the left ovary, while in 6% of the cases struma ovarii is bilateral. The malignant transformation is a
BACKGROUND
Malignant struma ovarii is an extremely rare ovarian tumour containing malignant thyroid carcinoma within differentiated thyroid tissue, as the predominant tissue type. Surgery for suspected ovarian tumour and incidental pathological diagnosis is the most common presentation. Evidence
Ovarian tumors presented with ovarian mass in childhood and adolescence are uncommon but an important part of gynecological cases. Struma ovarii is one of the rare cystic benign ovarian tumors that is observed predominantly in women who are between the ages of 40 and 60 years old. It is extremely
Authors of this research present 3 cases of struma ovarii diagnosed in postoperative histopathological examination in years 1994-1997. The first one was accidentally discovered during examination of a woman in menopausal period, the second was a case of 39-years old woman with hyperthyroidism and
A 58-year-old woman was found to have metastatic thyroid cancer in her liver. This was identified when she was investigated for upper abdominal pain and underwent biopsy of hepatic lesions. She had no palpable thyroid nodule and had a normal ultrasound of the thyroid. Previously, both ovaries had
Struma ovarii is rare ovarian tumor that is characterized by the presence of at least 50% thyroid tissue on histologic examination. This usually benign neoplasm is predominantly found in women between the ages of 40 and 60 years and infrequently in the pediatric age group. In the foregoing report,
BACKGROUND
Struma ovarii (SO) is a specialized monodermal teratoma predominantly composed of mature thyroid tissue, accounting for approximately 5% of all ovarian teratomas. Thyrotoxicosis is seen in about 8% of patients with SO. Most SO cases are benign with only 5-10% being malignant, and
BACKGROUND
We report a case of follicular struma ovarii observed in an ovary teratoma without metastatic dissemination.
METHODS
A right ovarian tumor was discovered at ultrasound examination in a 31-year-old woman complaining of low abdominal pain. The patient underwent laparoscopic exploration and
A 19-year-old woman at 12th week of pregnancy was referred to our hospital with severe acute abdominal pain, nausea and vomiting. Patient's abdomen was untreatable. Routine examinations, except neutrophilic leukocytosis, were normal. Ultrasound imaging showed the presence of intrauterine pregnancy
