Two cases of Brenner tumor of the vagina were encountered in postmenopausal asymptomatic women who presented with polypoid lesions measuring 0.5 and 1.2 cm, respectively, in the upper and mid-vagina. DNA flow cytometry in one tumor showed a diploid histogram, and Ki-67 (MIB-1) proliferation marker was very low in both tumors. To the best of our knowledge, only two vaginal Brenner tumors have be...

Brenner tumor is a relatively uncommon neoplasm. It constitutes 1.4–2.5 % of all ovarian tumors and has a predilection for the postmenopausal women. Most Brenner tumors are benign, with only 2–5 % being malignant. The malignant components of the tumor, which show heterogeneous epithelial growth and atypia with intervening stroma, consist of transitional cells, squamous or undifferentiated carci...

BACKGROUND Borderline Brenner tumor of the ovary is a rare entity characterized by papillary structures with a fibro-vascular core, covered by a transitional epithelium, and by the absence of stromal infiltration. It is associated, by definition, with a benign component of Brenner tumor. CASE We report a case of a 68-year-old woman, with a right ovarian mass, whose morphology and immuno-profi...

Ovarian tumor composed only of Brenner tumor and struma ovarii is very rare; only 6 cases have been reported in the English literature, to the best of the author's knowledge. A 66-year-old woman underwent right oophorectomy because of torsion of right ovarian cyst. Macroscopically, the ovarian cyst was hemorrhagic and red. Cystic content was hemorrhagic fluid. Microscopically, the cyst walls we...

We report a case of a 74-year-old female, who underwent total abdominal hysterectomy with bilateral salpingo-oophorectomy due to a solid-cystic tumor of the right ovary. The histopathological diagnosis revealed a borderline Brenner tumor (BBT). After 25 disease-free months the patient was admitted to a hospital because of a tumor in the postoperative scar of the abdominal wall, later diagnosed ...
