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.[1][2][3]  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.[1][2]  The current preferred term for benign Brenner tumors of the ovary is transitional cell tumors.[2]  These tumors usually occur in women ages 40 to 60 years.[2]  Treatment usually consists of surgery to remove the tumor.[2][3]  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.[1]
