What is stroma in the ovary?
The stroma of the ovary is a unique type of connective tissue abundantly supplied with blood vessels, consisting for the most part of spindle-shaped stroma cells. These appear similar to fibroblasts. The stroma also contains ordinary connective tissue such as reticular fibers and collagen.
What does ovarian stroma produce?
Unlike ordinary connective tissue, ovarian stroma is highly cellular while supporting fibers (both reticular fibers and ordinary collagen) are inconspicuous. Stromal cells associated with maturing follicles may acquire endocrine function and secrete estrogens. The entire ovarian stroma is highly vascular.
Can ovarian stromal tumors be benign?
There are different types of ovarian sex cord stromal tumours (SCSTs). These can be non cancerous (benign) or cancerous (malignant). Granulosa cell tumours are the most common type.
What is ovarian stromal Luteoma?
An observation of a stromal luteoma of the ovary is reported. It is a rare tumor (only about thirty cases of it have been published yet), occurring mostly in post menopausal women. Endocrine symptoms and sometimes virilizing signs may be observed. Abnormal vaginal bleeding is the most frequent clinical manifestation.
What are stroma cells?
Listen to pronunciation. (STROH-mul sel) A type of cell that makes up certain types of connective tissue (supporting tissue that surrounds other tissues and organs).
What makes up the stroma?
Stroma is the connective tissue just below the surface of an organ. It is a special type of tissue that helps hold the other parts of the organ together. Stroma is made up of cells that give the tissue its strength and shape.
What cells are in the ovary?
An ovarian follicle consists of a developing oocyte surrounded by one or more layers of cells called follicular cells.
How is an ovarian stromal tumor treated?
These cancers are treated with surgery to remove the ovary with the tumor. Surgery is also used to stage and debulk the cancer, as needed. This may be followed by chemo or hormone therapy. Often, the chemo used is the same type used to treat germ cell tumors (PEB: cisplatin, etoposide, and bleomycin).
What are stromal cells?
Can cysts grow teeth and hair?
Dermoid cysts occur when tissue collects under the skin. These cysts may contain hair, teeth or nerves.
What is lutein cyst?
From Wikipedia, the free encyclopedia. Theca lutein cyst is a type of bilateral functional ovarian cyst filled with clear, straw-colored fluid. To be classified a functional cyst, the mass must reach a diameter of at least three centimeters.
Are stromal cells cancerous?
Tumor stroma, broadly defined as the non-cancer cell and non-immune cell components of tumors, is viewed traditionally as the structural components holding tumor tissues together.
What is the ovarian stroma?
The ovarian stroma is the substance of the ovary—a connective tissue that binds structures together and is enriched with blood vessels, cells, and several hundred thousand follicles.
What is ovarian stromal hyperthecosis?
Varying degrees of proliferation of ovarian stromal cells, potentially mimicking a neoplasm but without luteinization (stromal hyperthecosis refers to presence of luteinized cells in the stroma at a distance from the follicles) Typically seen in the sixth to seventh decade, less common in reproductive age
What can immunohistochemistry tell us about ovarian cancer?
Immunohistochemistry can be useful in the diagnosis of ovarian germ cell tumours and sex cord-stromal tumours. A wide variety of markers are available, including many that are novel.
Are ovarian fibromas associated with ovarian stromal neoplasms?
Our study results show that ovarian fibromas, fibrothecomas, and leiomyomas have a similar immunophenotype (positive for CD56, WT1, ER-beta, and PR) to that of ovarian stromal cells, supporting an ovarian stromal origin for these neoplasms.
