In this tumor thyroid tissues are present which covers almost more than 50 % of the total mass present. Struma ovarii is a rare entity consisting of thyroid components that are part of a teratoma or dermoid in the ovary. (2012). [] Although 5–15% of all ovarian teratomas may contain some thyroid tissue; only 2% of these are made exclusively of SO. Most patients were premenopausal, and the mean lesion diameter was 57.3 mm (range, 30‐95 mm). "Struma Ovarii" is a descriptor in the National Library of Medicine's controlled vocabulary thesaurus, MeSH (Medical Subject Headings).Descriptors are arranged in a hierarchical structure, which enables searching at various levels of specificity. Knoten ist nicht gleich Krebs. The most common thyroid-type malignancies to arise in struma ovarii are papillary and follicular carcinomas.

Radiographic features . Als Struma wird jede Schilddrüsenvergrößerung bezeichnet, unabhängig von Ätiologie und Stoffwechsellage der Schilddrüse. Struma ovarii is a monodermal variant of ovarian teratoma, which was initially described by Bottlin in 1888 and, later, by Pick in 1902 and 1903, who recognized that struma ovarii was composed of thyroid tissue.1 Malignancy of struma ovarii is rare. (2015). Struma ovarii is a variant of a germ cell tumor composed predominantly of thyroid tissue. Ovarian struma ovarii occurred in 12 (4.8%) of 251 cases of ovarian dermoid cysts. It most commonly occurs as part of a teratoma, but may occasionally be encountered with serous or mucinous cystadenomas. Malignant struma ovarii: a population-level analysis of a large series of 68 patients. Patients may present with abdominal mass and unusual symptoms due to thyrotoxicosis, or Meigs syndrome (ascites and pleural effusion). 1. Dujardin, M. I., Sekhri, P., & Turnbull, L. W. (2014). First described by Von Klden in 1895 and Gottschalk in 1899, struma ovarii is the most common type of monodermal teratoma, and comprises about 3.0% of all ovarian teratomas. A rare teratoid tumor of the ovary composed almost entirely of thyroid tissue, with large follicles containing abundant colloidOccasionally there are symptoms of hyperthyroidism. Mutations allow the cancer cells to grow and multiply uncontrollably to form new cancer cells, These tumors can invade nearby tissues and adjoining body organs, and even metastasize and spread to other regions of the body, Presence of a well-circumscribed tumor in the ovary; monodermal teratomas are generally benign, The tumors are cystic (fluid-filled) in nature, Generally, only one ovary is affected; but, involvement of both ovaries may be seen (bilateral teratoma), The tumors may range in size from a few cm to over 20 cm, Large tumors (size over 4 cm) can compress the surrounding structures or organs and give the sensation of an abdominal mass, Abdominal pain from large-sized ovarian tumors, Abdominal discomfort, heaviness, and tenderness (especially at the iliac fossa, which is an area near to the hip bone), Pelvic discomfort and pain; lower back pain, Frequent urination due to compression/pressure of the tumor, When metastasis is noted, it may result in weight loss, fatigue, and other systemic symptoms, Physical examination and complete medical history screening, Ultrasound scan of the pelvis: It is a non-invasive procedure that uses high frequency sound waves to produce real-time images, Transvaginal ultrasound: An ultrasound is inserted into the vagina and the mass is examined using sound waves, Abdominal and pelvic CT scan: It is a non-invasive procedure that provides more details of soft tissues, blood vessels, and internal organs, Pelvic MRI scan: It is a non-invasive medical test that uses a powerful magnetic field to produce images of soft tissues, bones, organs, and all other internal structures of the abdomen and pelvis, Hysteroscopy: This procedure involves placing a probe through the cervix to examine the cavity of the uterus, Laparoscopy: A special device is inserted through a small hole into the abdomen, to visually examine it.
