Non-small cell neuroendocrine carcinomas (NSCNEC) account for 2% of gynecological cancer cases and are associated with a poor prognosis due to delayed diagnosis and aggressive tumor behavior. BRCA2 -associated ovarian carcinomas predominantly possess a high-grade serous phenotype, which respond to platinum and targeted therapy with PARP inhibitors. Presented here is the case of an adult patient with NSCNEC of the ovaries associated with a deleterious BRCA2 germline mutation. The pathogenic mutation was also confirmed on the somatic level, while the wild-type allele had a high variant fraction, suggesting loss of heterozygosity...

Cases of squamous cell carcinoma (SCC) arising from ovarian endometriosis have been rarely reported. Most of the patients show a poor prognosis and present with a diminished survival time. We present a SCC case arising from endometriosis, and analyzed the clinical, therapeutic, and pathologic features through a comprehensive literature review. A 43-year premenopausal woman (gravida 2, para 1) presented to our hospital due to sudden pain in lower abdomen. Exploratory laparotomy indicated rupture of left ovarian cyst and intra-abdominal hemorrhage were observed...

The aim of this study was to assess whether there are differences between the results of determining oxidative stress markers obtained from different origin cell lines after exposure to chemicals generating free radicals. The studies considered two markers of oxidative stress: the level of thiobarbituric acid reactive substances (TBARS) and superoxide dismutase activity. The evaluation was performed in five cell lines: Chinese hamster ovary (CHO-9) cells, lung adenocarcinoma A549, macrophages RAW264.7, skin carcinoma cells A431, and keratinocytes HaCaT...

Synchronous endometrial and ovarian malignancies occur in 5% of women presenting with endometrial cancer and 10% of patients presenting with ovarian malignancy. When a high-grade serous carcinoma concurrently involves both ovary and endometrium, pathological determination of whether they are synchronous primaries or metastatic tumors from one primary site can be challenging. MicroRNAs (miRNA) are 22-nucleotide noncoding RNAs that are aberrantly expressed in cancer cells and may inherit their cellular linage characteristics...

The differentiation between a primary mucinous ovarian neoplasm and an extra-ovarian metastasis in the ovary is often challenging in the histopathologic practice. Among various ovarian metastases from the gastro-intestinal tract the low-grade appendiceal mucinous neoplasm (LAMN) is an important differential diagnosis to consider particularly in case of pseudomyxoma peritonei. A newly recognized marker in the routine diagnostic of a mucinous neoplasm in the ovary is SATB2 (Special AT-rich sequence-binding protein 2)...

Inguinal lymph node mass as the first sign in patients with ovarian cancer represents a rare situation, with only few cases being reported so far. We present the case of a 46-year-old patient who presented for the apparition of bilateral inguinal tumoral masses in the absence of any other pathological signs. The biopsy revealed the presence of an adenocarcinoma with probable genital origin; however, neither the gynaecological examination nor the computed tomography demonstrated the presence of any suspect lesion...

The telomerase reverse transcriptase (TERT) gene is highly expressed in stem cells and silenced upon differentiation. Cancer cells can attain immortality by activating TERT to maintain telomere length and telomerase activity, which is a crucial step of tumorigenesis. Two somatic mutations in the TERT promoter (C228T; C250T) have been identified as gain-of-function mutations that promote transcriptional activation of TERT in multiple cancers, such as melanoma and glioblastoma. A recent study investigating TERT promoter mutations in ovarian carcinomas found C228T and C250T mutations in 15...

PURPOSE: Small cell carcinoma of the ovary, hypercalcemic type (SCCOHT) is a rare, aggressive ovarian cancer in young women that is universally driven by loss of the SWI/SNF ATPase subunits SMARCA4 and SMARCA2. A great need exists for effective targeted therapies for SCCOHT. EXPERIMENTAL DESIGN: To identify underlying therapeutic vulnerabilities in SCCOHT, we conducted high-throughput siRNA and drug screens. Complementary proteomics approaches profiled kinases inhibited by ponatinib...

Cervical gastric-type adenocarcinomas are aggressive non-human papillomavirus-related carcinomas with a propensity for extracervical spread, including unusual sites such as the omentum, peritoneum, and ovary. We report 7 cases of cervical gastric-type adenocarcinoma with fallopian tube involvement predominantly in the form of mucosal colonization without underlying invasion. As far as we are aware, this has not been previously described and this report adds to the literature regarding metastatic neoplasms, which may exhibit tubal mucosal involvement and mimic an in situ lesion at this site...

Cancer is a complex genetic disease that can arise through the stepwise accumulation of mutations in oncogenes and tumor suppressor genes in a variety of different tissues. While the varied landscapes of mutations driving common cancer types such as lung, breast, and colorectal cancer have been comprehensively charted, the genetic underpinnings of many rare cancers remain poorly defined. Study of rare cancers faces unique methodological challenges, but collaborative enterprises that incorporate next generation sequencing, reach across disciplines (i...

Our previous study showed that 5-aza-2-deoxycytidine (5-aza-dC) could inhibit tumor growth by enhancing the susceptibility of ovarian clear cell carcinoma (OCCC) to paclitaxel through decreasing AKT/mTOR expressions. The objective of the study is to evaluate the antitumor efficacy of everolimus (RAD001) and 5-aza-2-deoxycytidine (5-aza-dC) by targeting AKT/mTOR and EZH2 in OCCC. Paclitaxel-sensitive and resistant OCCC cell lines were established. In vitro proliferative and apoptotic assays and flow cytometry were performed...

BACKGROUND: Sunitinib is a multiple receptor tyrosine kinase inhibitor (TKI) used for the treatment of renal cell carcinoma (RCC). It increases the median survival considerably with minimum side effects. Alopecia is one of the rare side effects. Metastasis to the ovary is also rare. We report a case of RCC metastasizing to the ovary developing alopecia early on starting sunitinib. CASE PRESENTATION: A 22-year-old hypothyroid girl underwent right radical nephrectomy for T2N0 RCC...

The SWItch Sucrose non-fermentable (SWI/SNF) complex is a highly conserved multi-subunit complex of proteins encoded by numerous genes mapped to different chromosomal regions. The complex regulates the process of chromatin remodelling and hence plays a central role in the epigenetic regulation of gene expression, cell proliferation and differentiation. During the last three decades, the SWI/SNF complex has been increasingly recognized as a central molecular event driving the initiation and/or progression of several benign and malignant neoplasms of different anatomic origin and having diverse histomorphological appearance...

OBJECTIVE: Many high-grade serous carcinomas initiate in fallopian tubes as serous tubal intraepithelial carcinoma (STIC), a microscopic lesion identified with specimen processing according to the Sectioning and Extensive Examination of the Fimbria protocol (SEE-Fim). Given that the tubal origin of these cancers was recently recognized, we conducted a survey of pathology practices to assess processing protocols that are applied to gynecologic surgical pathology specimens in clinical contexts in which finding STIC might have different implications...

We report a 72-year-old woman with rare metastases of gastric cancer to the bone, skin, and ovary occurring more than 8 years after distal gastrectomy, which were subsequently effectively controlled. Histopathological diagnosis revealed signetring cell carcinoma, and the comprehensive findings were pT4a, pN3, ly2, v0, and Stage III c. The adjuvant chemotherapy of S- 1 plus cisplatin(CDDP)was switched to S-1monotherapy for 4 years and then to tegafur/uracil(UFT)for an additional year. Eight years after the operation, I-CTP and alkaline phosphatase(ALP)levels were elevated, and bone scintigraphy revealed bone metastasis...

BACKGROUND: Non-small cell lung carcinomas (NSCLCs), mainly adenocarcinoma (AC) and squamous cell carcinoma (LSCC), account for about 80% of all lung cancer cases. One of the proteins involved in NSCLC progression may be special AT-rich binding protein 1 (SATB1), a potent transcriptional regulator, able to control the expression of whole sets of genes simultaneously. SATB1 has been found to be associated with aggressive phenotype and poor prognosis in numerous malignancies, including breast, colon, ovary and prostate cancer...

The most common hereditary gynaecological tumour syndromes are hereditary breast and ovarian cancer syndrome and Lynch syndrome. However, pathologists also may encounter gynaecological tumours in women with rare hereditary syndromes. Many of these tumours exhibit distinctive gross and microscopic features that are associated with a risk for an inherited gene mutation. The sensitivity and specificity of these tumour pathology features for predicting an inherited mutation vary depending on the syndrome. By recognising these tumour features, pathologists may potentially contribute to the diagnosis of an unsuspected syndrome by recommending referral of the patient for formal risk assessment by genetic counselling...
