Struma ovarii is a specialized type of mature teratoma of the ovary in which thyroid tissue makes up the predominant or only component of the tumor. The word “struma” is a Latin term that has historically referred to the thyroid gland. Most cases of struma ovarii are noncancerous and behave in a completely benign way. …

Hydrosalpinx is a noncancerous (benign) condition in which a fallopian tube becomes blocked at its outer end and fills with watery fluid. The fallopian tubes carry an egg from the ovary to the uterus. The name comes from two Greek words: “hydro” for water and “salpinx” for tube. The blockage is almost always at the …

A fibrothecoma is a noncancerous (benign) tumor of the ovary. It is made of a mixture of two cell types that are both normally found in the ovary. One is the fibroblast, a long, thin cell that forms the ovary’s firm supporting tissue. The other is the theca cell, a rounded hormone-producing cell that normally …

A thecoma is a noncancerous (benign) tumor of the ovary. It is made of cells that resemble theca cells, a normal cell type found in the ovary. Theca cells surround developing eggs and make hormones, and the cells in a thecoma often do the same. It belongs to a family of tumors called sex cord-stromal …

A borderline Brenner tumor of the ovary is an uncommon type of ovarian tumor that is not cancer, but is also not a completely benign growth. It belongs to a group of tumors called borderline tumors, which sit between clearly benign tumors and cancer. A borderline Brenner tumor is more complex than a benign Brenner …

What is a sex cord-stromal tumour? The term sex cord-stromal tumour (SCT) refers to a group of tumours that start from specialized sex cord or stromal cells normally found in the ovary. Types of ovarian tumours in this group include fibroma, thecoma, adult-type granulosa cell tumour, juvenile-type granulosa cell tumour, and Sertoli-Leydig cell tumour. Are …

Adult-type granulosa cell tumor is a rare type of ovarian cancer that develops from granulosa cells — specialized cells in the ovary that normally support egg development and produce the hormone estrogen. It is the most common type of sex cord-stromal tumor, a group of ovarian tumors that arise from the hormone-producing supporting cells of …

A mucinous cystadenofibroma is a noncancerous (benign) type of ovarian tumor. It consists of fluid-filled spaces called cysts, along with firm, fibrous supporting tissue. The cysts are lined by cells that produce a thick, gelatinous, mucus-like fluid called mucin. The name describes what the pathologist sees. “Cyst” refers to the fluid-filled spaces, “adeno” to the gland-like lining cells, …

Atrophy of the ovary means the ovary has become smaller and has lost most of its egg-producing tissue. Pathologists use atrophy to describe an organ that shrinks and loses functional tissue. Your report may also describe the ovary as atrophic, involuted, or postmenopausal. In the ovary, atrophy is usually a normal change rather than a …

A benign Brenner tumor is a noncancerous (benign) growth that starts in the ovary. Under the microscope, it is made of small nests of cells that resemble the lining of the urinary tract, called urothelial cells. These nests sit inside dense, firm supporting tissue called stroma. The tumor is named after Fritz Brenner, the pathologist …
