We report a case of anti-N-methyl-D-aspartate-receptor (anti-NMDAR) encephalitis associated with an immature teratoma developed in a 38-year-old woman. Positron emission tomography (PET) revealed focal intense uptake of F-fluorodeoxyglucose in an area of the brain corresponding to the right medial temporal lobe as well as an intrapelvic tumor. After the PET examination, the patient complained of disorientation and short-term memory loss. The ovarian tumor was resected and diagnosed as an immature teratoma. The cerebrospinal fluid analysis was positive for anti-NMDAR antibody...

BACKGROUND: Ovarian mature cystic teratomas (MCT) rarely transform to a primary primitive neuroectodermal tumor (PNET)(1). This case report offers evidence that MCTs may have undetected micro-focuses of malignant neural tumors. CASE: We describe the case of a 12-year-old female that presented with right-sided abdominal pain and distention. Intra-operative findings revealed a right ovarian MCT. However, pathology showed a 0.5 centimeter focus of malignant neural tumor within the 11 centimeter MCT...

We present an atypical case of relapsed anti-NMDAR encephalitis in a young female patient without an associated ovarian teratoma. She presented with recurrent seizure attacks with muscle weakness, psychosis, dyskinesia, autonomic failure and insomnia. She was first misdiagnosed as mitochondrial encephalomyopathy with lactic acidosis and stroke-like episodes (MELAS) then Hashimoto's encephalopathy due to diffuse cerebral lesions, elevated serum lactic acid concentration, increased amount of thyroid peroxidase and thyroglobulin antibodies in serum and diffuse lesions of the thyroid gland...

Background Ovarian cysts, which present as neoplastic and non-neoplastic lesions, are the most common gynaecological cause of hospital admissions. Early diagnosis is difficult due to asymptomatic nature. Clinical, radiological and gross examination alone cannot distinguish benign from malignant lesions, hence, histopathological examination is important for diagnostic, therapeutic and prognostic approach. Objective The objective of the study is to analyze the spectrum of ovarian cystic lesions with their clinico-morphorgical features...

Struma ovarii is a rare monodermal variant of ovarian teratoma that contains at least 50% thyroid tissue. Less than 8% of struma ovarii cases present with clinical and biochemical evidence of thyrotoxicosis due to ectopic production of thyroid hormone and only 5% undergo malignant transformation into a papillary thyroid carcinoma. Only isolated cases of hormonally active papillary thyroid carcinoma developing within a struma ovarii have been reported in the literature. We report the case of a 36-year-old woman who presented with clinical signs and symptoms of hyperthyroidism as well as a left adnexal mass, which proved to be a thyroid hormone-producing, malignant struma ovarii...

OBJECTIVES: The golden standard in treatment benign ovarian cysts is laparoscopic cystectomy, but it may also influence women's fertility. The aim of the study was to compare women's fertility after laparoscopic cystectomy of endometrioma versus other benign ovarian tumors. MATERIALS AND METHODS: Out of the 123 patients operated because of benign ovarian tumor (OT), 66 underwent laparoscopic cystectomy of endometrioma (endometrioma group) and 57 underwent laparoscopic cystectomy of other benign ovarian tumor like: functional cyst, hemorrhagic cyst, yellow body cyst or mature teratoma (reference group)...

BACKGROUND: Anti-N-Methyl-D-Aspartate receptor (anti-NMDAR) encephalitis is responsive to immunotherapy and removal of tumor, but there is no consensus in the treatment of severe anti- NMDAR encephalitis with prolonged refractory status epilepticus (SE). CASE REPORT: A 17-year-old girl presented as acute psychosis, refractory seizures, hyperkinesia, autonomic instability, and soon progressed to a dissociative state of coma. Anti-NMDAR antibodies were positive in serum and CSF...

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 malignant SO causing thyrotoxicosis is very uncommon. CASE: A 64-year-old woman had been diagnosed with thyrotoxicosis 2 years previously. The thyroid gland was palpable with a micronodular texture, and the patient was euthyroid under carbimazole...

Introduction. Carcinosarcoma is an uncommon form of ovarian cancers, classified as being part of the group of mixed epithelial and mesenchymal tumors. The occurrence of carcinosarcoma in association with a mature cystic teratoma and synchronous tubal carcinoma is very rare. Case Report. A 69-year-old woman presented with a pelvic mass. An abdominal computerized tomographic scan detected a 15 cm right pelvic mass which was suggestive of malignant transformation of a dermoid cyst. Intraoperative, bilateral ovarian masses (left 10 cm and right 12 cm) with diffuse peritoneal metastatic nodules were identified...

Androgen-secreting ovarian tumours are extremely rare accounting for <5% of all ovarian neoplasms. They are more frequent in postmenopausal women and should be suspected in the case of a rapid onset of androgenic symptoms. We report 4 cases of postmenopausal women who presented with signs of virilisation. All patients revealed increased serum levels of testosterone, normal dehydroepiandrosterone-sulfate and negative pelvic ultrasound for adnexal masses. An androgen-secreting ovarian tumour was suspected and all of them were submitted to bilateral oophorectomy...

BACKGROUND: Surgery followed by platinum-based chemotherapy is the standard of care for MOGCTs, except for stage IA dysgerminoma and stage IA grade 1 immature teratoma where surveillance only is recommended. The role of adjuvant chemotherapy and surgical staging is debated. PATIENTS AND METHODS: Data from 144 patients with stage I MOGTs were collected among MITO centers (Multicenter Italian Trials in Ovarian Cancer) and analysed. RESULTS: 55(38...

Ovarian epithelial inclusions lined by mucinous epithelium are rare and of uncertain origin. Ovaries containing such inclusions were studied in 42 women. The inclusions were divided into 3 groups: serous epithelial lined with typical ciliated morphology but with distinct basophilic cytoplasmic mucin in some or all of the lining cells, those lined by typical mucinous epithelium, and those lined by a combination of typical mucinous epithelium and serous epithelium. The mean patient age was 61.5 years. Pure mucinous inclusions were found in 27 patients, serous-type inclusions with cytoplasmic mucin in 20, and mixed type in 10...

Paraneoplastic syndromes are a heterogeneous group of clinical and biological manifestations caused by underling neoplasms. They can reveal ovarian teratoma which express neuroendocrine proteins, or contain mature or immature neural tissue inducing an autoimmune response. The etiological investigation is then crucial to early identification of the tumor in order to optimize the prognosis and to limit neurological sequelae. In case of ovarian teratoma, management is essentially based on surgical resection sometimes associated with immunotherapie...

BACKGROUND: Mature cystic teratoma (MCT) of the ovary is benign germ cell tumor and shows the highest incidence in women of reproductive age. Histologically, it includes components derived from endoderm, mesoderm, and ectoderm. Although there have been many reports of MCT having small part of the intestinal component, ovarian MCT containing complete colon structure was very rare. CASE PRESENTATION: A 54-year-old woman underwent laparoscopic left salpingo-oophorectomy due to an incidentally found ovarian mass...

BACKGROUND: Pediatric adnexal torsion is rare, can be challenging to recognize, and may result in ovarian loss. OBJECTIVE: We sought to identify and compare the defining characteristics of adnexal torsion in premenarchal and postmenarchal girls. METHODS: A retrospective cohort study was performed at a tertiary care children's hospital, including patients diagnosed postnatally with adnexal (ovarian or tubal) torsion between 1997 and 2013. Proportions were compared using relative risk regression...

An activating point mutation of the c-KIT tyrosine kinase receptor gene, D816H, has been described in germ cell tumors (GCTs). We report an adolescent diagnosed with an ovarian mixed GCT and systemic mastocytosis with chronic myelomonocytic leukemia (SM-CMML). The teratoma and dysgerminoma differed by copy number aberrations via single nucleotide polymorphism (SNP) microarray, but were inclusive of the same c-KIT D816H point mutation (c.2446G>C) also identified in blood and bone marrow mast cells. These findings indicate not only a clonal origin of the GCT and hematologic malignancy, but also suggest a rare KIT mutation may be playing a fundamental role in malignancy development...

BACKGROUND: Anti-N-methyl-D-aspartate receptor encephalitis is a recently discovered disease entity of paraneoplastic limbic encephalitis. It largely affects young women and is often associated with an ovarian teratoma. It is a serious yet treatable condition if diagnosed early. Its remedy involves immunotherapy and surgical removal of the teratoma of the ovaries. This case of anti-N-methyl-D-aspartate receptor encephalitis involves an early surgical intervention with bilateral oophorectomy, despite negative imaging evidence of a teratoma...

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...
