Methods the data of 286 patients admitted to hospital and followed up for more than ten months were analyzed retrospectively to study the clinicopathological characteristics and related factors of recurrence.
Ovarian sex cord-stromal tumors are uncommon neoplasms that typically present in the first two to three decades of life, with the exception of adult granulosa cell tumors, which typically present later, with risk for development peaking at age 50 to 55 years.
This article focuses on the general classification of ovarian tumors.
Women with ovarian cancer may have no symptoms or mild symptoms until the disease is in an advanced stage.
Historically, most theories of the pathophysiology of ovarian cancer included the concept that it begins with the dedifferentiation of the cells overlying the ovary.
On the other hand, malignant ovarian germ cell tumors (mogcts) account for only a small fraction of ovarian germ cell neoplasms. Interest in their clinical and histologic features has somewhat diminished in the last 2 decades, with relatively few clinicopathologic series reported. 1,2 this low priority may be a consequence of their fortunately good response to platinum-based chemotherapy.

Types of ovarian cancer there are three main types of ovarian tumors: epithelial tumors- derived from the cells on the surface of the ovary. This is the most common form of ovarian cancer and occurs primarily in adults. Germ cell tumors- derived from the egg producing cells within the body of the ovary. This occurs primarily in children and teens and is rare by comparison to epithelial ovarian tumors.
Like ovarian cancer, ppc tends to spread along the surfaces of the pelvis and abdomen, so it is often difficult to tell exactly where the cancer first started. This type of cancer can occur in women who still have their ovaries, but it is of more concern for women who have had their ovaries removed to prevent ovarian cancer.
Ovarian cancer types include: epithelial tumors, which begin in the thin layer of tissue that covers the outside of the ovaries. Stromal tumors, which begin in the ovarian tissue that contains hormone-producing cells.
Diagnosis and treatment of ovarian cancer are based on intraoperative pathology and debulking surgery. The development of a novel molecular tool is significant for rapid intraoperative pathologic diagnosis, which instructs the decision-making on excision surgery and effective chemotherapy. In this work, we represent a dna aptamer named mapoc46, which is generated from cell-selex by targeting.

Cancer center gynecologic pathologists were some of the first to discover that some ovarian tumors are not cancerous or precursors of cancer. These tumors, known as “low malignancy potential,” can often be removed by skilled gynecologic cancer surgeons without destroying a patient’s fertility.
Pathology of ovarian tumors most tumors of the ovary can be placed into one of three major categories—surface epithelial-stromal tu-mors, sex cord-stromal tumors, and germ cell tumors (fig. 1)—according to the anatomic structures from which the tumors presumably originate.
Comments: mural nodules are sometimes seen in borderline and malignant ovarian mucinous tumors. It is not entirely clear whether mural nodules evolve through divergent differentiation within a single mucinous neoplasm or represent a collision phenomenon between clonally unrelated tumors.
Serous cystadenoma: develop papillary growths which may be so prolific that the cyst appears solid. Mucinous cystadenoma: the most common large ovarian tumours which may become enormous.
This theory assumes that all ovarian surface epithelial tumors have the same origin for many years, pathologists diagnosed and classified ovarian epithelial tumors based on histological similarity, size, clinical information and apparent cell of origin; fallopian tubes were inadequately sampled and ignored controversies with the traditional view.

Surface epithelial-stromal tumors are a class of ovarian neoplasms that may be benign or malignant. Neoplasms in this group are thought to be derived from the ovarian surface epithelium (modified peritoneum) or from ectopic endometrial or fallopian tube (tubal) tissue.
“ovarian pathology in children is common and the pathology can be quite diverse. The most common benign ovarian tumor in childhood is a teratoma. In this article, we discuss the origin of these germ cell tumors followed by a complete discussion of ovarian pathology.
There are several subtypes of ovarian cancer, and identifying those types requires careful evaluation by highly specialized pathologists.
But, as the gynecologic pathologists at johns hopkins have discovered through years of research and diagnostic experience, ovarian cancer is neither simple nor is it straightforward.
There are more than 30 different types of ovarian cancer, which are classified by the type of cell from which they start.
Granulosa cell tumor; sertoli-leydig cell tumor; rare epithelial ovarian cancers. Clear cell carcinoma; mucinous carcinoma; low-grade serous carcinoma; transitional cell carcinoma; endometrioid carcinoma; tumors of low malignant potential (borderline tumors) carcinosarcoma.
Two of the main types of specimens received in pathology from ovarian cancer staging.
Ovarian tumors are generally asymptomatic, meaning a woman rarely has any noticeable symptoms. In some women, the tumor is so undetectable that it eventually grows large enough to cause pelvic or abdominal discomfort by encroaching on nearby organs.
Pdf abstract: a total of 102 cases of ovarian tumours were studied with aim to evaluate the frequency of histopathologically diagnosed ovarian tumor find.
Ovarian stromal tumors are derived from, or mimic in their growth patterns, constituents of specialized gonadal stroma: cortical and medullary stromal cells,.
Ovarian leydig cell tumors have been divided into two subtypes by some pathologists, the hilus cell tumor and the leydig cell tumor, nonhilar type. The former, which is much more common, originates in the ovarian hilus from hilar leydig cells, which have been identified in 80–85% of adult ovaries.
Surface epithelial-stromal ovarian tumors (60-70%): ovarian serous tumors. Ovarian serous cystadenoma: ~60% of serous tumors ovarian borderline serous cystadenoma: ~15% of serous tumors; ovarian serous cystadenocarcinoma: ~25% of serous tumors; commonest malignant ovarian tumor.
Histologic sections of the right and left adnexa show a high grade neoplasm growing in a solid trabecular pattern that involves both ovaries without capsular disruption. The tumor cells are positive for ck7 and pax8 with abnormal (overexpression) of p53 but negative for ck20.
Rare ovarian tumours displaying benign, borderline or proliferative, and malignant variants. They may be associated with mucinous cystadenoma and cystic teratoma.
Epithelial ovarian cancer, which arise from the surface of the ovary (the epithelium), is the most common ovarian cancer. Fallopian tube cancer and primary peritoneal cancer are also included within this designation. Germ cell ovarian cancer arises from the reproductive cells of the ovaries, and is rare. Stromal cell ovarian cancer, which arises from connective tissue cells, is very rare.
The gross pathology of ovarian cancers is very similar regardless of histologic type: ovarian tumors have solid and cystic masses.
Ovarian cancer treatment can reduce the effects of this type of cancer. Learn more about ovarian cancer treatment at discovery health. Advertisement if you have been diagnosed with ovarian cancer, the first line of treatment is almost alway.
Pathology of ovarian tumors most tumors of the ovary can be placed into one of three major categories— surface epithelial‐stromal tumors, sex cord‐stromal tumors, and germ cell tumors (fig. 1)—according to the anatomic structures from which the tumors presumably originate.
An introduction to the ovary is in the ovary article, which also deals benign cysts.
Ovarian cancer often goes undetected until it has spread within the pelvis and abdomen. At this late stage, ovarian cancer is more difficult to treat. Early-stage ovarian cancer, in which the disease is confined to the ovary, is more likely to be treated successfully. Surgery and chemotherapy are generally used to treat ovarian cancer.
Ogcts are rare tumors, accounting for 2% to 3% of all ovarian cancers and develop usually in young women. The median age for diagnosis is 16 to 20 (range 6 to 40 years). 1 ethnic and racial differences have been noted in an analysis extracted from the surveillance, epidemiology, and end results (seer) database, with increased incidence of ogcts among pediatric black females compared with black.
The second of us (wgm), as a practising gynaecological pathologist, especially found the “non-pathological” chapters interesting.
The article examines ovarian tumours including ovarian cancer. An introduction to the ovary is in the ovary article, which also deals benign cysts. What was labeled ovarian cancer in the past may really arise from fallopian tube. The label tubo-ovarian cancer has been advocated to address this change.
The incidence of ovarian cancer has decreased by about 1% per year since at least the mid-1970s among women younger than age 65, but only since the early 1990s in older women.
Germ cell tumors start from the cells that produce the eggs (ova). Stromal tumors start from structural tissue cells that hold the ovary together and produce the female hormones estrogen and progesterone. Some of these tumors are benign (non-cancerous) and never spread beyond the ovary.
Ovarian cancer has a significant effect on quality of life, psychological health and well-being. Interventions are available to help with the needs and social support. Many ovarian cancer survivors report a good quality of life and optimism. Others reported a spiritual change that helped them find meaning during their experience.
Primary ovarian mucinous carcinoma is a rare histologic subtype of epithelial ovarian carcinoma and exhibits considerable morphologic overlap with secondary tumour. Because of the histologic similarity between primary ovarian mucinous carcinoma and metastatic gastrointestinal carcinoma, it has been hypothesized that ovarian mucinous carcinomas.
Although germ cell tumors arise from primordial ovarian and testicular germ cells, the pathogenesis of the ovarian germ cell tumors is unknown.
Cancerous stromal growths, which include granulosa cell tumors (the most common type), granulosa-theca tumors, and sertoli-leydig cell tumors, can all secrete the reproductive hormone estrogen.
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.
Jun 1, 2016 the strongest risk factors are advancing age and family history of ovarian and breast cancer.
There is evidence that tumors in carriers may exhibit a distinct distribution of pathological features, but previous studies on the pathology of such tumors have been small. Our aim was to evaluate the morphologies and immunophenotypes in a large cohort of patients with familial ovarian cancer.
The world health organization histological classification for ovarian tumors separates ovarian neoplasms according to the most probable tissue of origin: surface epithelial (65%), germ cell (15%), sex cord-stromal (10%), metastases (5%), miscellaneous.
While the most common types of ovarian cancer are epithelial, germ cell and stromal tumors, some of the rarer types of ovarian cancer occur more than others. These include: ovarian sarcoma: unlike their carcinoma counterparts, ovarian sarcoma tumors develop in the connective tissues of ovarian cells.
