Although paratubal cysts are well-characterized incidental findings, paratubal serous borderline tumors are very rare, with only one case report in the literature. We describe here a 27-year-old, nulliparous, married woman with a paratubal serous borderline tumor. The patient presented with a huge pelvic mass accompanied by flank pain and underwent paratubal cystectomy and fertility-sparing sur...
Objective. The high temperature requirement factor A3 (HtrA3) is a serine protease homologous to bacterial HtrA. Four human HtrAs have been identified. HtrA1 and HtrA3 share a high degree of domain organization and are downregulated in a number of cancers, suggesting a widespread loss of these proteases in cancer. This study examined how extensively the HtrA (HtrA1-3) proteins are downregulated...
OBJECTIVE We performed a population-based analysis to compare the clinical characteristics of women with mucinous tumors with women with other epithelial tumors. STUDY DESIGN The Surveillance, Epidemiology, and End Results database was queried to identify all women with epithelial ovarian cancer diagnosed from 1988 to 2007. The natural history, clinical characteristics, and survival of women ...
BACKGROUND Ovarian cancer kills approximately 15,000 women in the United States every year, and more than 140,000 women worldwide. Most deaths from ovarian cancer are caused by tumors of the serous histological type, which are rarely diagnosed before the cancer has spread. Rational design of a potentially life-saving early detection and intervention strategy requires understanding the lesions w...
We Describe a case of ovarian serous cystadenoma having Sertoli-Leydig cell tumor, well differentiated, in the cystic septum. Well differentiated Sertoli-Leydig cell tumor coexisting with other tumor, including serous tumor, has not yet been described. In all cases of Sertoli-Leydig cell tumor with heterologous components or other tumors, the androblastomatous components are intermediately or p...
Diagnosis and treatment of epithelial ovarian cancer is challenging due to the poor understanding of the pathogenesis of the disease. Our aim was to investigate epigenetic mechanisms in ovarian tumorigenesis and, especially, whether tumors with different histological subtypes or hereditary background (Lynch syndrome) exhibit differential susceptibility to epigenetic inactivation of growth regul...
Purpose: Low-grade serous ovarian carcinomas (LGSC) are Ras pathway-mutated, TP53 wild-type, and frequently associated with borderline tumors. Patients with LGSCs respond poorly to platinumbased chemotherapy and may benefit from pathway-targeted agents. High-grade serous carcinomas (HGSC) are TP53-mutated and are thought to be rarely associated with borderline tumors. We sought to determine whe...
Ovarian cysts are an extremely common gynecological problem in adolescent. Majority of ovarian cysts are benign with few cases being malignant. Ovarian serous cystadenoma are rare in children. A 14-year-old presented with abdominal pain and severe abdominal distention. She underwent laparotomy and after surgical removal, the mass was found to be ovarian serous cystadenoma on histology. In concl...
nucleolar organizer regions are loops a/nuclear dna related to ribosomal dna, and their number in cells is believed to indicate cellular proliferative activity. using_a silver staining methodto visualize thesestructures inparaffin embeddedtissue sections, an attempt was made to determine ifthese agnor counts could be used as a diagnostic toolfor serous borderline tumors of the ovary. ten cases ...
The presence and location of carcinoembryonic antigen (CEA) was examined in tissue sections of 14 mucinous and 13 serous cystadenomas and cystadenocarcinomas of the ovary. CEA was demonstrated in the mucinous tumors but was not present in the serous tumors. In the mucinous tumors, CEA was located in the glycocalyx and apical portions of the absorptive-type epithelium, with only trace quantities...
