This leader reviews recent advances in immunohistochemistry that are useful in the diagnosis of ovarian neoplasms. These include the value of diVerent anticytokeratin antibodies in the distinction between a primary ovarian adenocarcinoma and a metastatic adenocarcinoma, especially of colorectal origin. These antibodies have also helped to clarify the origin of the peritoneal disease in most cas...

Ovarian yolk sac tumors (YSTs) are rare neoplasms. No radiological study has been done to compare the imaging findings between this type of tumor and other ovarian tumors. Here we analyzed the CT findings of 11 pathologically proven ovarian YSTs and compared their imaging findings with 18 other types of ovarian tumors in the same age range. Patient age, tumor size, tumor shape, ascites and meta...

Ovarian hemangioma is an uncommon ovarian tumor occurring in patients in different age groups. It is usually seen as small, asymptomatic mass, which is detected incidentally. On rare occasions, this type of tumor can be associated with other gynecological neoplasms. In this report, we present the clinicopathologic features of a case of ovarian hemangioma coexisting with multiple microscopic foc...

The fifth leading cause of cancer-related deaths among women in the United States is ovarian cancer. An estimated 21,980 new cases and 14,270 estimated deaths occurred nationwide in 2014. More than two-thirds of cases of ovarian cancer are diagnosed at stage III or IV when the peritoneal cavity or other organs are affected. Primary appendiceal malignant neoplasms may mimic advanced-stage ovaria...

this study was performed to determine the incidence and anatomo-pathological aspects of the reproductive system tumors in commercial laying hens. post mortem examination of 1041 laying hens revealed neoplasms of the ovaries and the oviduct in 52 (4.99%) cases. from these, ovarian adenocarcinoma was found in 14 cases, granulosa cell tumor in 7 cases, theca cell tumor in 1 case and marek's diseas...

malignant mixed germ cell tumors,though rare overall, are the most common type of malignant ovarian neoplasms in young and adolescent girls. these tumors are rapidly growing and can metastasize. we report a case of 13-yr-old girl who presented at shkm gmc, nalhar, mewat, haryana, india in december 2013 with huge abdominal lump of a malignant mixed germ cell tumor comprising both immature terato...

Ovarian borderline (low malignant potential) tumors are a puzzling group of neoplasms that do not fall neatly into benign or malignant categories. Their behavior is enigmatic, their pathogenesis unclear, and their clinical management controversial, especially for serous borderline tumors (SBT), the most common type of ovarian borderline tumor. Clarifying the nature of borderline tumors and thei...

Epithelial ovarian cancer is often considered a single pathological entity, but increasing evidence suggests that it is rather a group of different neoplasms, each with unique pathological characteristics, molecular features, and clinical behaviours. This heterogeneity accounts for the different sensitivity to antineoplastic drugs and makes the treatment of ovarian tumours a challenge. For earl...

With the evolution of the treatment of malignant neoplasms, the survival rates of patients undergoing chemo- or radiotherapy are increasing. The continuous development of techniques of assisted human reproduction has led to important strategies in an attempt to maintain reproductive function in patients subjected to treatment of neoplastic diseases, among them cryopreservation of embryos, gamet...
