Brenner Tumor of Ovary
Type of disease: Rare conditions
A Brenner tumor of the ovary is a small, firm, smooth and solid growth (tumor) on the ovary. Brenner tumors of the ovary usually do not cause symptoms. Approximately 2% of all ovarian tumors are Brenner tumors. There are three forms of this tumor: benign, proliferative (low chance of spreading beyond the original location of the tumor), and malignant. The current preferred term for benign Brenner tumors of the ovary is transitional cell tumors. These tumors usually occur in women ages 40 to 60 years. Treatment usually consists of surgery to remove the tumor. If a Brenner tumor has not spread into surrounding tissues or to more distant parts of the body, there is a good-to-excellent prognosis.
