Introduction: Dermoid cysts are rarely located in extraovarian sites, representing an extremely uncommon lesion of the round ligament. The differential diagnosis of an inguinal lesion that proved to be a dermoid cyst deriving from the round ligament is presented with a review of the literature Ovarian dermoid cyst and mature cystic ovarian teratoma are terms often used interchangeably to refer to the most common ovarian neoplasm. These slow-growing tumors contain elements from multiple germ cell layers and are best assessed with ultrasound Ovarian dermoid cysts are one of the commonest benign, pelvic tumours. However, presence of dermoid cysts at extraovarian locations is very rare. The extra-ovarian dermoid cysts can be of ovarian origin or may also originate from nonovarian sites like omentum, retroperitoneum, mediastinum, etc. We report one such rare case of extra-ovarian dermoid cyst observed in a 70-year-old postmenopausal.
Women with benign (non-cancerous) germ cell tumors such as mature teratomas (dermoid cysts) are cured by removing the part of the ovary that has the tumor (ovarian cystectomy) or by removing the entire ovary. Treating malignant germ cell tumor Most common ovarian tumour in pregnancy is Dermoid cyst Dermoid cyst is most prone to undergo torsion during pregnancy Extraovarian dermoid cysts arise occasionally in the lumbar region, uterovesical area, parasacral region and rectovaginal septum Epidermoid carcinoma (1.7%) and sarcomatous changes may occu Recognition of the most common benign ovarian and extraovarian adnexal masses should help avoid additional or unnecessary imaging. US features that suggest malignancy include thick septations, vascularized solid components, or areas of focal wall thickening, and identifying these features will result in timely management What are dermoid cysts? A dermoid cyst is an enclosed sac near the surface of the skin that forms during a baby's development in the uterus. The cyst can form anywhere in the body Dermoid cyst is a cystic tumor composed of well-differentiated components from at least two of the three germ cell layers (i.e., ectoderm, mesoderm and endoderm). It is more commonly seen in children less than two years old. CT and MR imaging show a complex, well-circumscribed cystic mass containing fluid, fat, and calcification
Anti-mullerian Hormone (AMH) After Treatment of Endometriomas With Alcohol Sclerotherapy Versus Surgery: Clinical Trial - Full Text View With a dermoid (Fig 2), the solid area is typically hyperechoic compared with the cyst wall and often has acoustic shadowing (17). In contrast, the mural nodule of other neoplasms usually has echogenicity similar to that of the cyst wall (4). Clot in a hemorrhagic cyst may occasionally mimic a solid nodule of a neoplasm INTRODUCTION Ovarian germ cell tumors (OGCTs) are derived from primordial germ cells of the ovary (figure 1). They may be benign or malignant. These neoplasms comprise approximately 20 to 25 percent of ovarian neoplasms overall, but account for only an approximate 5 percent of all malignant ovarian neoplasms [ 1-3 ] Extraovarian masses account for 2% to 10% of adnexal masses in surgical series. The majority of extraovarian adnexal masses are benign and most commonly are due to hydrosalpinges, paraovarian cysts, and peritoneal inclusion cysts The common causes of such extraovarian lesions that mimic ovarian pathology include fallopian tube diseases, paroaovarian cysts, peritoneal inclusion cysts, and a pedunculated or a broad ligament fibroid
. The strumal component was 12 cm or greater The adnexa are made up of the fallopian tubes and ovaries. Cysts are fluid-filled structures that can develop in the adnexa. Cysts on the ovaries are usually caused by hormonal stimulation or bleeding at the time of ovulation (hemorrhagic ovarian cysts). Most ovarian cysts require no treatment
Ovarian-Adnexal Reporting & Data System (O-RADS) O-RADS™ is an acronym for an Ovarian-Adnexal Imaging-Reporting-Data System which will function as a quality assurance tool for the standardized description of ovarian/adnexal pathology. The creation of a standardized lexicon permits the development of a practical, uniform vocabulary for. US O-RADS Key Lexicon Terms. 1.

. Detailed Description: Between 5-10% fertile women are affected by endometriosis, and ovarian endometrioma is present in 17-44% of cases, with 40% of patients with endometriomas being sterile. However, the gold standard treatment is laparoscopic ovarian cystectomy and this therapy. Cystic Extraovarian Lesions. When a cystic adnexal mass can be shown to be separate from the ipsilateral ovary (extraovarian), it is usually benign. Early fallopian tube carcinoma presenting when tubeconfined represents a very rare exception. The most common causes are peritoneal inclusion cysts, paratubal or paraovarian cysts, and hydrosalpinges
.1 and 13.2 ) As this is the first chapter considering ovarian tumors, some remarks concerning their evaluation are appropriate. Most of these comments are basic and familiar to experienced pathologists but may be occasionally forgotten with potential failure to frame Lesion localization (ie, ovarian versus extraovarian) • Lesion characterization (wide range of soft tissue contrast) T1-weighted imaging without and with fat saturation • Macroscopic fat of dermoid cyst • Endometrioma and endometriosis (homogeneously high signal on the fat-saturation T1-weighted sequence
Less common causes of cystic and solid nonovarian mimics of ovarian malignancy include mucocele of the appendix, lymphocele, spinal meningeal cysts, extraovarian endometriomas, extraovarian fibrothecomas, and gastrointestinal stromal tumors (Table 1). Identifying a normal appearing ovary is the key in distinguishing an extraovarian pelvic mass. A large ovarian tumor with no apparent extraovarian primary tumor. Large metastatic tumors in the ovary may dwarf a small primary tumor, e.g. large bilateral Krukenberg tumors due to a tiny occult gastric primary.

Coexistent extraovarian and bilateral ovarian dermoid cysts:a case presenting as an acute abdome Paraovarian cystadenoma is a usually benign adnexal tumor that does not arise from the ovary. There is an association with Von Hippel Lindau syndrome. Radiographic features Pelvic ultrasound typically seen as a unilateral cystic adnexal lesion.. Dermoid cysts are made up of cells you had since before you were born. Your body uses these cells to produce dermal tissue so they may contain fat, skin, hair, or even teeth Dermoid cysts (teratomas) - These complex ovarian cysts or mass are formed from the eggs produced and are often filled with pieces of bone, teeth, hair, and cartilage. They are usually benign and may grow to six inches in diameter. They may not be malignant, however, they can cause excessive pain due to twisting of the ovaries as a result of. ..

Cystic teratoma is the most common ovarian neoplasm. It consists of well-differentiated derivatives of germ cell layers (i.e., ectoderm, mesoderm, and endoderm) developing as hair, muscle, teeth, or bone. These tumors are generally benign but may undergo a malignant transformation in 1% to 2% of the cases extraovarian endometriosis,asithas similarsymptoms, such as pain and infertility. Diagnosing it is also helpful to ensure adequate surgical intervention. Endometriotic lesions fre-quently involve the surface of the peritoneum and ovary. Fat-suppressed images are useful to identify the lesion, but The only way to distinguish if a woman has Adnexal cyst, is through the pelvic exam. During the pelvic exam, the physician will feel the woman's vagina, ovaries, uterus, rectum and bladder. The physician will take note of any felt lump or any unusual things present. In doing this exam, the physician will use the speculum to make the vagina.
The association of ovarian teratoma and anti-N-methyl-D-aspartate receptor (NMDAR) encephalitis is a serious and potentially fatal pathology that occurs in young women and that is under-recognized. Our objectives were to analyze prevalence and outcome of this association, and increase awareness over this pathology. MEDLINE and SCOPUS for all studies published prior to November 30, 2013. The mature teratoma is by far the most common ovarian germ cell tumor. It is a benign tumor that usually affects women of reproductive age (teens through forties). It is often called a dermoid cyst because its lining is made up of tissue similar to skin (dermis). These tumors or cysts can contain different kinds of benign tissues including.
Extraovarian metastases are also present in at least 90% of the cases. One-third of patients die within 1 year, and 75% within 5 years. As many as 25% of patients, however, may remain asymptomatic for years postoperatively, with relief of the carcinoid syndrome 81 Malignant Transformation of Ovarian Dermoid Cyst Citation: Sarah Neary., et al..

The risk of malignant change appears to be related to age, with the highest incidence being in the 5th and 6 decades. Squamous cel . Struma ovarii accompanied by periton-eal or systemic dissemination but without malignant histological manifestations is termed peritoneal strumosis, which is controversial and problematic . Its pathologic examination shows multiple nodules of mature thyroi PATHOLOGY OF OVARIAN TUMORS. Most tumors of the ovary can be placed into one of three major categories— surface epithelial-stromal tumors, sex cord-stromal tumors, and germ cell tumors (Fig. 1 )—according to the anatomic structures from which the tumors presumably originate. Each category includes a number of subtypes Laparoscopy is the method of choice in operating benign masses of the ovary, while the risk and benefits on borderline or low malignant potential ovarian masses remains inconclusive. Dermoid cyst can be safely operated by laparoscopy, preferably by preventing cyst ruptured. The risk of rupturing an ovarian cyst during laparoscopy will depends.
Mature cystic teratomas (also called dermoid cysts) account for about 30-45 % of all ovarian neoplasms and around 60 % of all benign tumours arising in the ovary.1 Malignant transformation of the various mature tissue components of a dermoid cyst is rare and the reported incidence is 0.17-1.4 %.2,3 Squamous cell carcinoma (SCC), arising from the ectodermal component, is the commonest form. Two hundred and eighty-nine women were diagnosed with a total of 323 dermoid cysts by a single expert ultrasound operator. 93/289 (32.2%; 95% CI, 26.8-37.6%) women with 105/323 (32.5%; 95% CI, 27.

An adnexal mass is a growth that occurs in or near the uterus, ovaries, fallopian tubes, and the connecting tissues. They're usually benign, but are sometimes cancerous Ovarian epithelial neoplasms are remarkably similar to epithelial cells from extraovarian sites in the female reproductive tract. The three most common subtypes of these tumours, referred to as serous, endometrioid, and mucinous, are morphologically identical to carcinomas of the fallopian tube, endometrium, and endocervix, respectively the assessment of larger masses and extra-ovarian disease.3 The use of colour flow Doppler has generally not been shown to significantly improve diagnostic accuracy 27-29 but the combined use of the transvaginal route in combination with colour flow mapping and 3D imaging may improv
BOTs form a separate entity within the group of ovarian tumours. BOTs can be divided according to their epithelialcharacteristics as serous (50%),mucinous (46%),and mixed, endometrioid, clear cell, or Brennertumors (3.9%). Serous BOTs are bilateral in 30%of patients and can be associated with extraovarian lesions (so-called implants) in 35% Struma ovary is a monodermal ovarian teratoma which contains mature thyroid tissue. We present an unusual case of papillary carcinoma arising in struma ovarii. A 52 year old post menopausal lady presented with a large right adnexal mass preoperatively diagnosed as a dermoid cyst. She underwent staging laparotomy and the histopatholgy report showed follicular variant of papillary carcinoma. Neoplastic cells were not seen in the extraovarian sites, except for the left para-aortic lymph node.

Although the ovary is the most common origin of an adnexal mass, the source can also be the fallopian tubes, the uterus, and even bowel. From any of these organs, a mass can result from hypertrophy, neoplasm, or infection

Autoamputation of the appendix has rarely been described in the literature. We present a case of a pelvic mass, thought to be a dermoid cyst based on preoperative imaging. After surgical removal and pathological examination, the mass was found to be a chronic pelvic abscess containing the right adnexa as well as an autoamputated vermiform appendix enteric, dermoid, urogenital, traumatic, or infectious genesis . The origin of extra-ovarian mucinous cystic neoplasms (MCN) has been attributed to implanted or ectopic ovarian tissue, supernumerary ovaries or monolineage development of a component of a teratoma .

Epithelial ovarian cancer is the leading cause of death from gynecologic cancer in the United States. Of about 21,650 women diagnosed in 2008, 15,520 will die of this disease. 1 Epithelial ovarian cancer comprises more than 90% of malignant ovarian neoplasms. The other two types are germ cell tumors and sex cord stromal tumors Malignant degeneration of benign cystic teratoma of the ovary is rare. Occurrence of melanoma in an ovarian cystic primary teratoma in the absence of a demonstrable extraovarian primary is even rarer. We describe here one such case.
