Case report A 62-year-old white female, nulligravida, 10 years post-menopause, was admitted to hospital because of a low abdominal mass discovered upon routine gynaecological examination. Physical examination on admission was unremarkable except for the presence of a movable mass located in the left lower abdomen. At exploratory laparotomy, a left ovarian tumour was discovered and total abdomin...

Microscopically, ovarian malignant Brenner tumor shows components of malignant transitional cell tumor intermixed with benign and borderline elements. We report a case of this tumor with components that transition from benign to malignant on diffusion-weighted images (DWI) and in histologic findings. The benign component showed low signal intensity on T(2)-weighted images, whereas the malignant...

Borderline Brenner tumors represent quite a rare entity of ovarian tumors (about 2%) that develop from the surface ovarian epithelium. They are formed from papillary structures made of fibrovascular conjunctive axes covered by a transition epithelium, similar to the urinary bladder epithelium. According to the WHO classification, Brenner tumors present the following forms: benign, borderline an...

BACKGROUND Brenner tumors are relatively rare ovarian neoplasms with very few reported cases associating these tumors and urothelial carcinomas with different characteristics and particularities. CASE REPORT We report an unusual clinical case of borderline unilateral Brenner tumor of the ovary associated with a highly recurrent diffuse low-grade papillary urothelial carcinoma of the upper and...

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...

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...
