A rare teratoid tumor of the ovary composed almost entirely of thyroid tissue, with large follicles containing abundant colloid. Occasionally there are symptoms of hyperthyroidism. 5-10% of struma ovarii become malignant, the only absolute criterion for which is the presence of metastasis. (Dorland, 27th ed; Segen, Dictionary of Modern Medicine, 1992)
A tumor consisting of displaced ectodermal structures along the lines of embryonic fusion, the wall being formed of epithelium-lined connective tissue, including skin appendages, and containing keratin, sebum, and hair. (Stedman, 25th ed)
The triad of benign FIBROMA or other ovarian tumors with ASCITES, and HYDROTHORAX due to large PLEURAL EFFUSIONS.
General term for CYSTS and cystic diseases of the OVARY.
Tumors or cancer of the OVARY. These neoplasms can be benign or malignant. They are classified according to the tissue of origin, such as the surface EPITHELIUM, the stromal endocrine cells, and the totipotent GERM CELLS.
Neoplasms composed of more than one type of neoplastic tissue.
A smooth, solid or cystic fibroepithelial (FIBROEPITHELIAL NEOPLASMS) tumor, usually found in the OVARIES but can also be found in the adnexal region and the KIDNEYS. It consists of a fibrous stroma with nests of epithelial cells that sometimes resemble the transitional cells lining the urinary bladder. Brenner tumors generally are benign and asymptomatic. Malignant Brenner tumors have been reported.
Cell surface proteins that bind pituitary THYROTROPIN (also named thyroid stimulating hormone or TSH) and trigger intracellular changes of the target cells. TSH receptors are present in the nervous system and on target cells in the thyroid gland. Autoantibodies to TSH receptors are implicated in thyroid diseases such as GRAVES DISEASE and Hashimoto disease (THYROIDITIS, AUTOIMMUNE).
A true neoplasm composed of a number of different types of tissue, none of which is native to the area in which it occurs. It is composed of tissues that are derived from three germinal layers, the endoderm, mesoderm, and ectoderm. They are classified histologically as mature (benign) or immature (malignant). (From DeVita Jr et al., Cancer: Principles & Practice of Oncology, 3d ed, p1642)
Neoplasms composed of primordial GERM CELLS of embryonic GONADS or of elements of the germ layers of the EMBRYO, MAMMALIAN. The concept does not refer to neoplasms located in the gonads or present in an embryo or FETUS.
A genus of gram-negative, facultatively anaerobic, rod-shaped bacteria that occurs in fish and other aquatic animals and in a variety of mammals, including man. Its organisms probably do not belong to the normal intestinal flora of man and can cause diarrhea.
A malignant ovarian neoplasm, thought to be derived from primordial germ cells of the sexually undifferentiated embryonic gonad. It is the counterpart of the classical seminoma of the testis, to which it is both grossly and histologically identical. Dysgerminomas comprise 16% of all germ cell tumors but are rare before the age of 10, although nearly 50% occur before the age of 20. They are generally considered of low-grade malignancy but may spread if the tumor extends through its capsule and involves lymph nodes or blood vessels. (Dorland, 27th ed; DeVita Jr et al., Cancer: Principles & Practice of Oncology, 3d ed, p1646)
Degenerative or inflammatory conditions affecting the central or peripheral nervous system that develop in association with a systemic neoplasm without direct invasion by tumor. They may be associated with circulating antibodies that react with the affected neural tissue. (Intern Med 1996 Dec;35(12):925-9)

Follicular carcinoma in a functioning struma ovarii. (1/30)

We describe a case of follicular carcinoma in a functioning struma ovarii, which presented as an ovarian mass in a patient who had undergone a near-total thyroidectomy for a benign lesion. She underwent bilateral salpingo-oophorectomy and received radiotherapy and L-thyroxine treatment with no evidence of metastases in 4 years follow-up.  (+info)

Cystic struma ovarii: a rare presentation of an infrequent tumor. (2/30)

CONTEXT: Struma ovarii, a rare neoplasm, is a monophyletic teratoma composed of thyroid tissue. It is generally considered to account for less than 5% of mature teratomas. CASE REPORT: A diagnosis of struma ovarii may be the source of many diagnostic problems. It may be cystic and microscopic examination may only reveal a few typical thyroid follicles, resulting in confusion with other cystic ovarian tumors. Extensive sampling should be undertaken and immunohistochemistry may be decisive in establishing the thyroid nature of the epithelial lining. The authors report two cases of cystic struma ovarii, and discuss diagnostic criteria and the limitations of frozen biopsies in these tumors.  (+info)

A struma ovarii with increased serum basement membrane components: a case report. (3/30)

We report a case of struma ovarii with hyperthyroidism and elevated serum concentrations of type IV collagen and laminin. Circulating levels of type IV collagen and laminin were measured using specific radioimmunoassays (RIAs) for 7S collagen and the P-1 fragment of laminin, and the basement membrane components in the tumor were investigated by immunohistochemical analysis. Strong immunohistochemical staining specific for type IV collagen and for laminin was observed to be localized in the follicular walls. The serum levels of these antigens, as determined by RIA, were very high before removal of the tumor but decreased rapidly postoperatively. The present findings suggest that struma ovarii produces large amounts of type IV collagen and laminin. In addition, elevated levels of thyroid hormones might enhance the turnover of the basement membrane in various tissues.  (+info)

Sonographic and clinical characteristics of struma ovarii. (4/30)

Our objective was to evaluate the preoperative clinical, laboratory, and sonographic characteristics of struma ovarii in comparison to ovarian dermoid cysts. A retrospective review of gynecologic patients operated on for mature cystic teratoma over a 10 year period identified 12 cases of struma ovarii. These cases, combined with 4 additional cases from an earlier report, were the subject of this study. Results were compared to 32 cases of ovarian dermoid cysts. Ovarian struma ovarii occurred in 12 (4.8%) of 251 cases of ovarian dermoid cysts. Most patients were premenopausal, and the mean lesion diameter was 57.3 mm (range, 30-95 mm). Struma ovarii occurred more frequently (68.8%) in the right adnexa and was seen with a normal CA-125 level. Blood flow, assessed by Doppler ultrasonography, was located in the center of the lesion in all cases of struma ovarii. Rare cases were seen with elevated tumor markers and low resistance blood flow. With regard to dermoid cysts, blood flow had a higher resistive index. In addition, no blood flow could be detected from the center of the echoic lesion in dermoid cysts (P < 0.0001). In summary, it is difficult to distinguish between struma ovarii and dermoid cysts on the basis of their sonographic appearance. Nevertheless, Doppler flow may aid in the preoperative diagnosis of struma ovarii. Blood flow signals, detected from the center of the echoic lesion, and low resistance to flow may be more common in struma ovarii.  (+info)

Ovarian strumal carcinoid--report of a case that matastasized. (5/30)

Ovarian teratomas are known for their ability to form a wide variety of tissues. One unusual example of this potential is the strumal carcinoid in which the thyroid tissue is found in intimate association with carcinoid tumor. Although considered as a malignant transformation of struma ovarii, it is almost always benign. We report a rare case of strumal carcionid in a 44 year old lady who had metastasis in the contralateral ovary, myometrium and lungs.  (+info)

Coexistence of Graves' disease and struma ovarii: case report and literature review. (6/30)

We report a rare case of Graves' disease associated with struma ovarii. A 26-year-old Japanese woman had preexisting Graves' disease and was positive for TSH receptor antibody. She had been on antithyroid medication at presentation. She noted a mass in the lower left abdomen, which was diagnosed as a left struma ovarii by radiological work-up including computed tomography, magnetic resonance imaging and scintigraphy. The surgically excised teratomatous tumor, containing cystic spaces with thyroid tissue, was histologically proved to be struma ovarii. Since thyroid function tests and TSH receptor antibody did not change after surgery, her hyperthyroidism was considered to be due to Graves' disease. Our case was diagnosed as struma ovarii before surgery using various imaging studies.  (+info)

Hypothyroidism following struma ovarii tumor resection: a case report. (7/30)

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 ovarii. After 6 days, she developed weakness, myalgia, somnolence, nausea, and arterial hypotension. Laboratory tests showed a high level of thyroid-stimulating hormone (TSH) and a decreased level thyroxin. Thyroxin replacement therapy was initiated, and the patient became completely asymptomatic. This is the first reported case of a previously asymptomatic woman who developed a definite clinical hypothyroidism after resection of a struma ovarii tumor.  (+info)

Malignant struma ovarii. (8/30)

Malignant struma ovarii is a rare form of ovarian germ cell tumors. Because of its rarity, diagnosis and management of the tumor has not been clearly defined. A 52-year-old female with follicular variant of papillary carcinoma arising in struma ovarii is presented. There was no evidence of clinical malignancy or metastases. However on the basis of histopathologic findings, the case was diagnosed as malignant struma ovarii. It was accepted as stage Ia tumor and no other treatment was considered after radical excision. Due to its fairly good prognosis, surgical excision has been the preferred treatment for those who do not have disseminated disease. Nevertheless, long-term follow-up is necessary to determine the course of the disease.  (+info)

Struma ovarii is a rare type of ovarian tumor, which is composed predominantly of thyroid tissue and accounts for less than 1% of all ovarian neoplasms. It is classified as a specialized form of monodermal teratoma (a type of germ cell tumor). Despite being composed mainly of thyroid tissue, struma ovarii may produce and release thyroid hormones, leading to symptoms associated with hyperthyroidism in some cases.

Struma ovarii can be asymptomatic or present with various symptoms such as abdominal pain, distension, or menstrual irregularities. In rare instances, it might undergo malignant transformation into a thyroid-like carcinoma known as strumal carcinoid or thyroid carcinoma of the ovary. The definitive diagnosis is usually established through histopathological examination following surgical resection.

A dermoid cyst is a type of benign (non-cancerous) growth that typically develops during embryonic development. It is a congenital condition, which means it is present at birth, although it may not become apparent until later in life. Dermoid cysts are most commonly found in the skin or the ovaries of women, but they can also occur in other areas of the body, such as the spine or the brain.

Dermoid cysts form when cells that are destined to develop into skin and its associated structures, such as hair follicles and sweat glands, become trapped during fetal development. These cells continue to grow and multiply, forming a sac-like structure that contains various types of tissue, including skin, fat, hair, and sometimes even teeth or bone.

Dermoid cysts are usually slow-growing and may not cause any symptoms unless they become infected or rupture. In some cases, they may cause pain or discomfort if they press on nearby structures. Treatment typically involves surgical removal of the cyst to prevent complications and alleviate symptoms.

Meigs syndrome is a rare medical condition characterized by the combination of ovarian tumor (most commonly fibroma or thecoma), ascites (abnormal accumulation of fluid in the abdominal cavity), and pleural effusion (fluid accumulation around the lungs). The hallmark feature of this syndrome is that all these symptoms resolve after the removal of the ovarian tumor.

It's important to note that not all women with ovarian tumors will develop Meigs syndrome, and its exact cause remains unclear. It primarily affects middle-aged women and is typically diagnosed through imaging tests (such as ultrasound or CT scan) and the exclusion of other possible causes of ascites and pleural effusion.

After surgical removal of the ovarian tumor, the ascites and pleural effusion usually resolve on their own within a few months. Meigs syndrome is not considered a malignant condition, but regular follow-ups are necessary to monitor for any potential recurrence of the ovarian tumor or development of other health issues.

An ovarian cyst is a sac or pouch filled with fluid that forms on the ovary. Ovarian cysts are quite common in women during their childbearing years, and they often cause no symptoms. In most cases, ovarian cysts disappear without treatment over a few months. However, larger or persistent cysts may require medical intervention, including surgical removal.

There are various types of ovarian cysts, such as functional cysts (follicular and corpus luteum cysts), which develop during the menstrual cycle due to hormonal changes, and non-functional cysts (dermoid cysts, endometriomas, and cystadenomas), which can form due to different causes.

While many ovarian cysts are benign, some may have malignant potential or indicate an underlying medical condition like polycystic ovary syndrome (PCOS). Regular gynecological check-ups, including pelvic examinations and ultrasounds, can help detect and monitor ovarian cysts.

Ovarian neoplasms refer to abnormal growths or tumors in the ovary, which can be benign (non-cancerous) or malignant (cancerous). These growths can originate from various cell types within the ovary, including epithelial cells, germ cells, and stromal cells. Ovarian neoplasms are often classified based on their cell type of origin, histological features, and potential for invasive or metastatic behavior.

Epithelial ovarian neoplasms are the most common type and can be further categorized into several subtypes, such as serous, mucinous, endometrioid, clear cell, and Brenner tumors. Some of these epithelial tumors have a higher risk of becoming malignant and spreading to other parts of the body.

Germ cell ovarian neoplasms arise from the cells that give rise to eggs (oocytes) and can include teratomas, dysgerminomas, yolk sac tumors, and embryonal carcinomas. Stromal ovarian neoplasms develop from the connective tissue cells supporting the ovary and can include granulosa cell tumors, thecomas, and fibromas.

It is essential to diagnose and treat ovarian neoplasms promptly, as some malignant forms can be aggressive and potentially life-threatening if not managed appropriately. Regular gynecological exams, imaging studies, and tumor marker tests are often used for early detection and monitoring of ovarian neoplasms. Treatment options may include surgery, chemotherapy, or radiation therapy, depending on the type, stage, and patient's overall health condition.

Neoplasms are abnormal growths of cells or tissues in the body that can be benign (non-cancerous) or malignant (cancerous). When referring to "Complex and Mixed Neoplasms," it is typically used in the context of histopathology, where it describes tumors with a mixture of different types of cells or growth patterns.

A complex neoplasm usually contains areas with various architectural patterns, cell types, or both, making its classification challenging. It may require extensive sampling and careful examination to determine its nature and behavior. These neoplasms can be either benign or malignant, depending on the specific characteristics of the tumor cells and their growth pattern.

A mixed neoplasm, on the other hand, is a tumor that contains more than one type of cell or tissue component, often arising from different germ layers (the three primary layers of embryonic development: ectoderm, mesoderm, and endoderm). A common example of a mixed neoplasm is a teratoma, which can contain tissues derived from all three germ layers, such as skin, hair, teeth, bone, and muscle. Mixed neoplasms can also be benign or malignant, depending on the specific components of the tumor.

It's important to note that the classification and behavior of complex and mixed neoplasms can vary significantly based on their location in the body, cellular composition, and other factors. Accurate diagnosis typically requires a thorough examination by an experienced pathologist and may involve additional tests, such as immunohistochemistry or molecular analysis, to determine the appropriate treatment and management strategies.

A Brenner tumor is a rare type of benign (non-cancerous) ovarian tumor that originates from the tissue that lines the ovary (the epithelium). These tumors are typically small, slow-growing, and asymptomatic, although in some cases they may cause abdominal discomfort or bloating.

Brenner tumors are composed of transitional cells, which are similar to the cells found in the urinary bladder. They are usually solid and contain areas of calcification (calcium deposits). While most Brenner tumors are benign, a small percentage may become malignant (cancerous) and spread to other parts of the body.

The exact cause of Brenner tumors is not known, but they are more common in older women and are often found incidentally during routine pelvic exams or imaging studies. Treatment typically involves surgical removal of the tumor, and the prognosis is generally excellent, especially for benign tumors.

Thyrotropin receptors (TSHRs) are a type of G protein-coupled receptor found on the surface of cells in the thyroid gland. They bind to thyroid-stimulating hormone (TSH), which is produced and released by the pituitary gland. When TSH binds to the TSHR, it activates a series of intracellular signaling pathways that stimulate the production and release of thyroid hormones, triiodothyronine (T3) and thyroxine (T4). These hormones are important for regulating metabolism, growth, and development in the body. Mutations in the TSHR gene can lead to various thyroid disorders, such as hyperthyroidism or hypothyroidism.

A teratoma is a type of germ cell tumor, which is a broad category of tumors that originate from the reproductive cells. A teratoma contains developed tissues from all three embryonic germ layers: ectoderm, mesoderm, and endoderm. This means that a teratoma can contain various types of tissue such as hair, teeth, bone, and even more complex organs like eyes, thyroid, or neural tissue.

Teratomas are usually benign (non-cancerous), but they can sometimes be malignant (cancerous) and can spread to other parts of the body. They can occur anywhere in the body, but they're most commonly found in the ovaries and testicles. When found in these areas, they are typically removed surgically.

Teratomas can also occur in other locations such as the sacrum, coccyx (tailbone), mediastinum (the area between the lungs), and pineal gland (a small gland in the brain). These types of teratomas can be more complex to treat due to their location and potential to cause damage to nearby structures.

Neoplasms, germ cell and embryonal are types of tumors that originate from the abnormal growth of cells. Here's a brief medical definition for each:

1. Neoplasms: Neoplasms refer to abnormal tissue growths or masses, which can be benign (non-cancerous) or malignant (cancerous). They result from uncontrolled cell division and may invade surrounding tissues or spread to other parts of the body through a process called metastasis.
2. Germ Cell Tumors: These are rare tumors that develop from the germ cells, which give rise to sperm and eggs in the reproductive organs (ovaries and testes). They can be benign or malignant and may occur in both children and adults. Germ cell tumors can also arise outside of the reproductive organs, a condition known as extragonadal germ cell tumors.
3. Embryonal Tumors: These are a type of malignant neoplasm that primarily affects infants and young children. They develop from embryonic cells, which are immature cells present during fetal development. Embryonal tumors can occur in various organs, including the brain (medulloblastomas), nervous system (primitive neuroectodermal tumors or PNETs), and other areas like the kidneys and liver.

It is essential to note that these conditions require professional medical evaluation and treatment by healthcare professionals with expertise in oncology and related fields.

"Plesiomonas" is a genus of gram-negative, facultatively anaerobic, rod-shaped bacteria that are commonly found in aquatic environments. The most well-known species is Plesiomonas shigelloides, which is a potential human pathogen. It can cause gastroenteritis, with symptoms such as diarrhea, abdominal cramps, nausea, and vomiting. The bacteria are often transmitted through the consumption of contaminated food or water. However, it's worth noting that Plesiomonas infections are relatively rare and are more commonly seen in tropical and subtropical regions.

Dysgerminoma is a type of germ cell tumor that develops in the ovaries. It is a malignant (cancerous) tumor that primarily affects girls and women of reproductive age, although it can occur at any age. Dysgerminomas are composed of large, round, or polygonal cells with clear cytoplasm and distinct cell borders, arranged in nests or sheets. They may also contain lymphoid aggregates and may produce hormones such as estrogen or testosterone.

Dysgerminomas are usually unilateral (affecting one ovary), but they can be bilateral (affecting both ovaries) in about 10-15% of cases. They tend to grow and spread rapidly, so early detection and treatment are crucial for a favorable prognosis.

The standard treatment for dysgerminoma is surgical removal of the affected ovary or ovaries, followed by chemotherapy with agents such as bleomycin, etoposide, and cisplatin (BEP). With appropriate treatment, the five-year survival rate for patients with dysgerminoma is high, ranging from 80% to 95%.

Paraneoplastic syndromes of the nervous system are a group of rare disorders that occur in some individuals with cancer. These syndromes are caused by an immune system response to the cancer tumor, which can lead to the damage or destruction of nerve cells. The immune system produces antibodies and/or activated immune cells that attack the neural tissue, leading to neurological symptoms.

Paraneoplastic syndromes can affect any part of the nervous system, including the brain, spinal cord, peripheral nerves, and muscles. Symptoms vary depending on the specific syndrome and the location of the affected nerve tissue. Some common neurological symptoms include muscle weakness, numbness or tingling, seizures, memory loss, confusion, difficulty speaking or swallowing, visual disturbances, and coordination problems.

Paraneoplastic syndromes are often associated with specific types of cancer, such as small cell lung cancer, breast cancer, ovarian cancer, and lymphoma. Diagnosis can be challenging because the symptoms may precede the discovery of the underlying cancer. A combination of clinical evaluation, imaging studies, laboratory tests, and sometimes a brain biopsy may be necessary to confirm the diagnosis.

Treatment typically involves addressing the underlying cancer with surgery, chemotherapy, or radiation therapy. Immunosuppressive therapies may also be used to manage the immune response that is causing the neurological symptoms. While treatment can help alleviate symptoms and improve quality of life, paraneoplastic syndromes are often difficult to cure completely.
