Mucinous tumors of the ovary: a clinicopathologic study of 196 borderline tumors (of intestinal type) and carcinomas, including an evaluation of 11 cases with “pseudomyxoma peritonei.” Am J Surg Pathol 2000 ;24(11):1447–1464.

Gynecologists and obstetricians typically encounter borderline ovarian tumors in the course of managing adnexal masses. In contrast to invasive epithelial ovarian cancers, borderline tumors are more likely to occur in premenopausal women and are more likely to be stage I, …

With tumors of this kind, the usual course of treatment is to surgically remove the growth and conduct a biopsy. The structure of Se hela listan på cancerresearchuk.org Most borderline ovarian tumours are classified as serous from their appearance under the microscope. A smaller number have a different appearance and are called mucinous. Sometimes a small, undetected mucinous tumour can develop in the appendix, and spread to the ovary. Borderline ovarian tumors (BOTs) form a separate entity within the group of epithelial ovarian tumors acknowledged by the International Federation of Gynecology and Obstetrics (FIGO) in 1961 and adopted by the World Health Organization (WHO) in 1973. Serous and mucinous borderline ovarian tumors are the two most common types, while endometrioid, Brenner, and clear cell borderline ovarian tumors are much less common.

"Mucinous tumor of low malignant potential (borderline or atypical proliferative tumor) of the ovary: a study of 171 cases with the assessment of intraepithelial carcinoma and microinvasion.". Int J Gynecol Pathol 30 (3): 218-30. Borderline tumors of the ovary (BOT) were described for the first time by Taylor in 1929. These lesions have a more favorable outcome than do other ovarian cancers. What is a borderline ovarian tumour? Borderline ovarian tumours are abnormal cells that form in the tissue covering the ovary.

Since BOT were first identified >40 years ago, they have inspired controversies disproportionate to their incidence. Ovarian borderline tumors have also been referred to as “tumors of low malignant potential” or “atypical proliferative tumors”; however “borderline tumor” is the preferred terminology. Borderline tumors exhibit epithelial proliferation and cytologic atypia, beyond that acceptable for a benign neoplasm, but do not exhibit the destructive growth seen in carcinomas.

It is also hypothesized that persistent infection with C. trachomatis, or other microorganisms, might initiate/promote ovarian tumor development. READ MORE

In 1929, Taylor identified serous borderline tumors of the ovary (SBT) as a group of epithelial tumors charac- terized by a relatively good prognosis when compared with other ovarian cancers.' Subsequently, these neo- plasms were defined by the World Health Organization as tumors that show epithelial proliferation greater than

Borderline tumors of the ovary (also called tumors of low malignant potential) are a heterogeneous group of lesions defined histologically by atypical epithelial proliferation without stromal invasion . The behavior of these tumors is distinct from low-grade ovarian carcinoma, and they are considered a distinct clinical entity. Se hela listan på emedicine.medscape.com Ovarian borderline tumors have also been referred to as “tumors of low malignant potential” or “atypical proliferative tumors”; however “borderline tumor” is the preferred terminology. Borderline tumors exhibit epithelial proliferation and cytologic atypia, beyond that acceptable for a benign neoplasm, but do not exhibit the destructive growth seen in carcinomas. A borderline tumor, sometimes called low malignant potential tumor, is a distinct but yet heterogeneous group of tumors defined by their histopathology as atypical epithelial proliferation without stromal invasion. It generally refers to such tumors in the ovary but borderline tumors may rarely occur at other locations as well.

They occur in younger women, are present at an early stage, and have a favorable prognosis, but symptomatic recurrence and death may be found as long as 20 years after therapy in some patients. Ovarian low malignant potential tumor is a disease in which abnormal cells form in the tissue covering the ovary. Signs and symptoms of ovarian low malignant potential tumor include pain or swelling in the abdomen. Tests that examine the ovaries are used to diagnose and stage ovarian low malignant potential tumor. Borderline ovarian tumors (BOT) are uncommon but not rare epithelial ovarian neoplasms, intermediate between benign and malignant categories.

Background . Serous borderline tumor represents a group of noninvasive tumor of the ovary bridging between benign serous cystadenoma and serous carcinoma. They are commonly seen in younger women and usually have an excellent outcome but seldom show local recurrence (J.
