Abstract:

El pseudomixoma peritoneal (PMP) es una condición patológica pobremente entendida, caracterizada por la presencia de ascitis mucinosa relacionada a siembras peritoneales multifocales. Múltiples estudios histopatológicos que incluyeron inmunohistoquímica han sugerido que la mayoría de los PMP, si no todos los casos, derivan de adenomas mucinosos del apéndice más que de lesiones primarias del ovario. Pocos estudios que han evaluado la biología molecular y la genética del PMP se han reportado recientemente; sin embargo, estos trabajos solo han analizado un pequeño número de casos, incluyendo mues

La mayoría no presenta síntomas o complicaciones del embarazo, y el diagnóstico se realiza en forma accidental por ecografía de rutina.

Background: Ovarian tumor and tumor like conditions are seen in women from early childhood to post-menopausal age. The ovaries are a pair of female sex glands responsible for the germ cell maturation, storage and release; cyclically. It also plays an important role in steroidogenesis. The ovaries are a totipotential structure and hence, neoplasms from all 3 germinal layers can be seen arising from it and manifesting clinically as ovarian tumors and tumor like conditions with its occurrence more during the late reproductive life.

Abstract:

Krukenberg tumor is a malignancy of ovary that metastasizes from a primary site. Krukenberg tumors are uncommon and account for less than 2% of all ovarian tumors. It is usually a bilateral involvement of ovaries from the metastatic deposit from adenocarcinoma of the stomach. Krukenberg tumors mostly occur after 40 years. Metastatic ovarian tumors in young age are very rare. Here, we reported a very rare case of bilateral Krukenberg tumors of the ovaries arising from a primary adenocarcinoma of the stomach in a 20 year old Indian female.

Abstract:

Testes and ovarian tumors are tumors which appear in small percentages in dogs. They rarely lead to a lethal outcome in animals, but, due to the different clinical manifestations that can accompany these tumors, their timely diagnosis is significant because it often determines the treatment of the animal in which such tumors were diagnosed. During the period from 1999 until 2003, the Department for Pathological Morphology of the Belgrade Faculty of Veterinary Medicine examined macroscopically and pathohistologically 5 ovaries with macroscopic signs of neoplastic changes from 5 female and 25 ne

Abstract:

Epithelial ovarian cancer is the leading cause of death from gynecologic cancer and the fifth most common cause of cancer mortality in women in the United States. Fewer than 40% of women with ovarian cancer are cured, and 70% of patients present with advanced disease; because of the location of the ovaries, ovarian cancer has been difficult to diagnose at earlier stages. Epidemiologic studies have identified risk factors, including family history. The NCCN guidelines discuss epithelial ovarian cancer as well as less common ovarian histopathologies, including germ cell neoplasms, carcinosarcoma

The most common presenting signs or symptoms of malignant lymphomas involving the ovaries are abdominal or pelvic pain or mass.
