Although mature ovarian teratoma (MOT) is one of the most commonly detected benign tumours worldwide, its malignant transformation is rare. This article presents a case of a 47-year-old woman, operated on for emergency reasons due to a giant painful ovarian tumour, showing preoperatively no signs of malignancy. Surprisingly, a pathological report showed MOT coexisting with an early-stage ovarian adenocarcinoma developing as an endophytic papilloma.

In 50% of female patients, AMNs (particularly LAMNs) have a tendency to metastasize to organs in the genital tract, where the neoplasm can mimic the features of primary ovarian mucinous cancer (POMC). The present case report reviewed the difficulties in differentiating between these two types of tumors.

We aimed to assess the staining patterns of selected CKs (CK7, CK19, CK20, CK AE1/AE3) in 74 patients with coexisting AEH and EC by independently analyzing both morphological variables. Specimens were collected from women with AEH and EC who underwent surgical interventions between 2012 and 2019 at the Department of Obstetrics and Gynecology of Vilnius University Hospital "Santaros Klinikos" in Vilnius, Lithuania.

Although different genetic mechanisms have been shown to be involved in ovarian carcinogenesis, the role of introns methylation is still unresolved. We performed methylation analysis of introns 1, 3, and 4 of the to identify patterns in primary stage III OCs, corresponding metastases, and healthy tissues.

Patients And Methods: We investigated the incidence of HPV16 DNA E6/E7 transcripts in 47 type I (endometrioid-type) tumors and eight type II (non-endometrioid-type) uterine neoplasms applying PCR-based technology. Immunohistochemical staining in HPV16 positive cases was also performed, and seven lymph node metastases were examined for the presence of HPV16 DNA E6/E7.
Endometrial cancer is the most common gynaecological malignancy in developed countries. Over 382,000 new cases were diagnosed worldwide in 2018, and its incidence and mortality are constantly rising due to longer life expectancy and life style factors including obesity. Two major improvements are needed in the management of patients with endometrial cancer, i.

Given that over 90% of cancer deaths are caused by invasive and metastatic lesions, countless factors and multiple theories have been proposed as the triggering factor for the cascade of actions of cancer invasion. However, those factors and theories are largely based on the studies of cell lines or animal models.

Herein, we presented synchronous early stage G1 adenocarcinoma of the uterine corpus with cervical G2 endometrioid adenocarcinoma. Although both neoplasms displayed the same histological subtype, they differed significantly according to the histological grading or clinical stage of the disease.

Although existing evidence supports a fertility-sparing treatment in the case of tumors <2 cm in diameter, the approach is less clear in bulky early-stage CC. In addition, the outcomes of radical trachelectomy performed by minimally invasive techniques are also highly debatable.

The aim of the present retrospective study was to compare the immunohistochemical proliferation markers [Ki67, proliferating cell nuclear antigen (PCNA), minichromosome maintenance complex component 3 (MCM3), and topoisomerase IIα (topoIIα)] assessment in both components of UC. A total of 30 paraffin-embedded slides of UCs, obtained from patients who underwent surgery between January 1, 2006, and December 31, 2020, were analyzed.

Ureteric injuries at laparoscopic hysterectomies are incidental and occur in less than 1% of cases. They can be identified intra-operatively but most of them are undetected.

The available literature provides evidence for the involvement of 32 genes in the hereditary incidence of EC. The physiological markers of EC and coexisting diet-dependent maladies include antioxidative system disorders but also progressing inflammation; hence, the main forms of prophylaxis and pharmacotherapy ought to include a diet rich in substances aiding the organism's response to this type of disorder, with a particular focus on ones suitable for lifelong consumption.

This encouraged us to conduct a retrospective analysis of CC treatment surgical approaches applied to the patients at tertiary level Vilnius University Hospital Santaros Clinics, Vilnius, Lithuania, between 2009 and 2019. : The retrospective study was carried out to evaluate the outcomes after 28 laparoscopic and 62 laparotomic radical hysterectomies for early cervical cancer in a single tertiary care institution performed during the period 2009-2019.

CKs play a critical role in determining epithelial structural integrity under stressful conditions in addition to their various fundamental functions in cellular proliferation, apoptosis, migration, adherence and molecular signaling. Immunohistochemical CKs staining could be evaluated with a proper comprehension of their task limitations and their association with the normal morphology to avoid misdiagnosis.

The study reports the assessment of iNKT cells in peripheral blood and tissue of benign and borderline ovarian tumors (BOTs) and in the advanced-stage ovarian cancer. The study groups were as follows: 25 women with benign ovarian tumors, 11 women with BOTs, and 24 women with primary advanced-stage ovarian cancers.

Intense nuclear staining in the uterine adenomyoma tissue showed an immunoreaction with BAF250a/ARID1A, Arginase-2 as well as 1LRH-2E1/NR5A2, suggesting a role of these proteins and transcriptional activity of their genes in uterine polypoid adenomyoma development. Neither Nidogen-2 nor SF-1/NR5A1 were expressed in UPA.

Research and analysis of factors that affect male fertility are limited, especially, regarding the age of the father and determining the age at which quality of semen decreases. Age of the father has greater impact than maternal age, on cases of sporadic autosomal dominant congenital diseases such as Apert, Crouzon, Pfeiffer, Noonan and Costello syndromes, multiple endocrine neoplasia (types 2A and 2B) and achondroplasia.
