Ovarian neoplasms consist of several histopathologic entities, and treatment depends on the specific tumor type. Epithelial ovarian cancer comprises most malignant ovarian neoplasms (~ 80%)1; however, other less-common pathologic subtypes must be considered in treatment guidelines. The NCCN Clinical Practice Guidelines in Oncology (NCCN Guidelines) for Ovarian Cancer discuss epithelial ovarian ...
Steroidogenic acute regulatory (StAR) protein is a rate-limiting protein, which is essential for transporting cholesterol into the mitochondria for steroidogenesis. StAR protein could be a marker for steroidogenic tissues. In this study, we investigated StAR protein levels in sex-cord stromal tumors (SCSTs) including 31 adult granulosa cell tumors, 3 juvenile granulosa cell tumors, 10 fibrothec...
Sex-cord stromal tumours account for only about 6% of testicular neoplasms.' Leydig cell tumour is the commonest sub-type but other tissues that can be represented in varying amounts and degrees of differentiation include Sertoli, granulosa and theca-lutein elements. Testicular granulosa-cell tumour ofthe adult type is particularly uncommon. This report details a mixed sex-cord stromal tumour o...
Granulosa cell tumors (GCTs) are rare sex cord-stromal tumors that have been studied for decades. However, their infrequency has delayed efforts to research their etiology. Recently, mutations in human GCTs have been discovered, which has led to further research aimed at determining the molecular mechanisms underlying the disease. Mouse models have been important tools for studying GCTs, and ha...
Background: Tumors of the central nervous system (CNS) are a heterogeneous group of neoplasms with different prevalence in different sex and age groups and various parts of CNS. Objectives: Determining the relative frequency of different types of CNS tumors in different ages, sex and CNS anatomical locations. Materials and Methods: This retrospective study was performed using pathological repor...
Objective: The majority of childhood ovarian masses are benign. However, malignant tumors encountered in adulthood may also be seen childhood. There is still no tumor management protocol for children. We shared our experiences with mass cases operated clinic. Material and Methods: Patients aged 0-18 years had surgery hospital between 2010 2020 due to were included the study. ages patients, maxi...
Uterine sex cord-like tumor (USCLTs) is a type of very rare cancer. It’s originally divided into two subtypes: type I and type II, and it is very similar with real sex cord tumor. A 47-year-old Chinese woman; 7 years after total hysterectomy, pelvic masses had been found for 6 years. Transabdominal bilateral adnexa resection, greater omentum resection and pelvic lymph node dissection were perfo...
BACKGROUND Ovarian granulosa cell tumors (GCTs) are the most common type of potentially malignant ovarian sex cord-stromal tumor. GCTs often produce estrogen and/or progesterone; consequently, symptoms related to hyperestrogenism are common at diagnosis. Nonspecific symptoms or signs associated with this neoplasm include amenorrhea and changes in various sex hormone levels, which can be hard to...
