ovarian teratoma

Hanna R Goldberg, Lisa Allen, Sari Kives
BACKGROUND: Fetiform teratoma, a highly differentiated mature cystic teratoma resembling a fetus, is rare and typically found in the ovaries of women of reproductive age. This report describes the youngest case of ovarian fetiform teratoma. CASE: A 7-year-old female presented with acute abdominal pain. Radiological examinations revealed a 5.2 cm ovarian complex cystic mass with fetal-like components in favour of fetus-in-fetu (FIF) and teratoma. Following surgical removal, the mass resembled a fetus consisting of a head, two eye slits, two small upper limb projections, and hair...

STUDY OBJECTIVE: To compare the rates of oophorectomy performed by pediatric surgeons for benign indications before and after the addition of a gynecologist to the surgical staff of a children's hospital. Study Design, Participants, Intervention and Outcome Measure: Retrospective chart review of patients ages 5-21 who underwent surgical management by pediatric surgeons for benign adnexal indications. Patient characteristics and clinical outcomes were recorded. Rates of oophorectomy for cases managed prior to the addition of a gynecologist (1998-2004) were compared to those managed after a gynecologist joined the surgical staff (2005-2013)...

BACKGROUND: While ovarian mature cystic teratomas are benign ovarian germ-cell tumors and the most common type of all ovarian tumors, the formation of fistulas into surrounding organs such as the bladder and the intestinal tract is extremely rare. This report documents a case of ovarian mature cystic teratoma with a rectal fistula, thought to be caused by local inflammation. CASE DESCRIPTION: A pelvic mass was diagnosed as an ovarian mature cystic teratoma of approximately 10 cm in diameter on transvaginal ultrasound and magnetic resonance examinations...

Granular cell tumors involving the female reproductive tract are rare, with only a small number of cases described. Of the reported cases, none are documented within an ovarian mature cystic teratoma (MCT). This report documents a case of a granular cell tumor, incidentally discovered within an ovarian MCT in a 50-yr-old woman undergoing a supracervical hysterectomy and left salpingo-oophorectomy. Although malignant transformation and other secondary ovarian neoplasms in MCT have been well documented, synchronous nonovarian benign neoplasms are reported much less frequently...

Background: Immature teratoma (IT) is a tumor containing immature neuroectodermal tissue, primarily in the form of neuroepithelial tubules. However, the diagnosis of IT containing only cellular neuroglial tissue (CNT) without distinct neuroepithelial tubules is often difficult, since the histological characteristics of immature neuroectodermal tissues remain unclear. Here, we examined the significance of CNT and defined immature neuroectodermal tissues by comparing the histological features of neuroglial tissues between mature teratoma (MT) and IT...

Anti-N-methyl-d-aspartate-type glutamate receptor autoimmune encephalitis can arise in the setting of ovarian teratoma and often responds to resection. When it occurs in the absence of tumor, failure to respond to treatment may be more likely, and affected patients often require intensive care. To further understand the mechanisms and potential management, we present findings from an autopsy conducted on a young woman who died of refractory autoimmune encephalitis of this type. Rituximab was administered 70 days before death, and both 37 and 14 days before death, CD19(+) lymphocytes were only 0...

OBJECTIVE: Anti-N-methyl-d-aspartate receptor encephalitis is a rare but emerging cause of autoimmune encephalitis. Our objective is to present a case of this rare disease while highlighting the importance of an aggressive search for underlying malignancy as well as the common mischaracterization of primary psychiatric illness that occurs in these patients. METHODS: A young Caucasian female with no known psychiatric history presented with acute onset of seizures and psychosis...

A 13-year-old, obese girl presented with acute abdominal pain with abdominal distension for a year. The physical examination revealed marked abdominal distension with a large well-circumscribed mass sized 13×20 cm. Her body mass index (BMI) was 37.8 kg/m2. An abdominal CT scan revealed a huge multiloculated cystic mass and a left adnexal mass. She had an abnormal fasting plasma glucose and low HDL-C. Laparotomy, right salpingooophorectomy, left cystectomy, lymph node biopsies and partial omentectomy were performed...

Recently, the search for diagnostic antibody markers has drawn considerable attention in relation to autoimmune encephalitis. Among the antibody markers, the most frequently detected is the anti-N-methyl-D-aspartate receptor (NMDAR)antibody. Patients with this antibody develop characteristic clinical features. This disease tends to affect young women, and starts with psychiatric symptoms followed by seizures, involuntary movements, autonomic failure, and respiratory failure. Nearly half of these female patients have ovarian teratoma...

Extragonadal teratomas are rare, and localization in the endometrium and cervix is exceptional, with fewer than 10 case reports documented so far in the English literature. We report here the case of a 46-year-old patient who presented with simultaneous immature teratoma in the endometrium and mature teratomas in the ovary in association with gliomatosis peritonei but with no evidence of gestational origin; she subsequently developed multiple solid mature teratomas in the cervix and parauterine tissue. No other similar cases have been previously reported to our knowledge...

INTRODUCTION: Ovarian neuroendocrine tumors are extremely rare. In the ovary, the term of neuroendocrine tumor is usually related to carcinoid tumors although it may be sometimes applied to neuroendocrine carcinomas of non-small cells or small cells cancers usually occurring in the lungs. These carcinoid tumors may develop de novo or from other tumors including teratomas. CASE REPORT: We report a patient who presented with an ovarian carcinoid tumor developed, near or from a dermoid cyst, which was original by its mode of discovery in the dermatology department...

Gliomatosis peritonei (GP) is characterized by the presence of benign, mature neuroglial implants throughout the peritoneum and is typically accompanied by mature or immature ovarian teratomas. GP is a condition that has only been described relatively recently, with ~100 cases reported in the English literature. The majority of reported cases have focused on the pathology and clinical treatment of the disease; radiological findings are distinct, but the discussion of this is scarce in the literature. The current study presents two cases of GP with bilateral ovarian teratomas and provides a review of the relevant literature, with particular emphasis on the radiological differential diagnosis...

BACKGROUND: Anti-N-methyl-D-aspartate receptor encephalitis is an autoimmune disorder characterized by behavioral changes, dyskinesia, and autonomic instability. PATIENT DESCRIPTION: We describe a 14-year-old girl who initially presented with acute behavioral changes and seizures and who over a 2-week period developed high fever, tachycardia, and elevated blood pressures. RESULTS: Because she received multiple medications including anticonvulsants and a neuroleptic, our patient was initially diagnosed with neuroleptic malignant syndrome, a disorder characterized by autonomic dysfunction, hyperthermia, muscle rigidity, and mental status changes usually caused by the use of a neuroleptic agent...

One of the most extraordinary stories in the chronicles of gynecologic cancers has been that of malignant ovarian germ cell tumors. Prior to the mid-1960s, most patients died of disease. Fifty years later, most survive. Precisely because high cure rates are achievable, the concentration over the past decade has been on minimizing toxicity and late effects. The present review focuses on five areas of interest related to the management of malignant ovarian germ cell tumors that highlight the different therapeutic strategies practiced by pediatric and gynecologic oncologists: 1) primary surgery, 2) surgery alone (surveillance) for patients with FIGO stage IA disease, 3) postoperative management of FIGO stage IC-III disease, 4) postoperative management of pure immature teratoma, and 5) postoperative management of metastatic pure dysgerminoma...

Our knowledge of testicular germ cell neoplasms has progressed in the last few decades due to the description of germ cell neoplasia in situ (GCNIS) and a variety of specific forms of intratubular germ cell neoplasia, the discovery of isochromosome 12p and its importance in the development of invasiveness in germ cell tumors (GCTs), the identification of specific transcription factors for GCTs, and the recognition that a teratomatous component in mixed GCT represents terminal differentiation. Isochromosome 12p and 12p overrepresentation, collectively referred to as 12p amplification, are fundamental abnormalities that account for many types of malignant GCTs of the testis...

The purpose of this work was to evaluate cases of benign ovarian mature teratoma (MT) with enhancing solid components on pelvic magnetic resonance imaging (MRI) and to correlate the MRI findings with the pathology reports. We retrospectively reviewed MRI findings and pathologic reports of 126 patients with pathologically confirmed ovarian MT. Enhancing solid components were observed in 24 (18.8%) of 128 benign MTs. The largest diameter ranged from 5.9 to 42.2 mm. The appearance was variable. Of 24 tumors, 19 (79...
