Malignant brenner tumor of ovary.
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...
متن کاملMalignant Brenner tumor of the ovary: Review and case report
Ovarian neoplasms are a heterogeneous group of tumors with varying incidence in the general population. The most common are the surface epithelial tumors which include transitional cell tumors. Transitional cell tumors include both transitional cell carcinoma and Brenner tumor. The vast majority of Brenner tumors are benign, often incidental findings; however, malignant Brenner tumors (MBT) do ...
متن کاملGenetic studies on lung tumor susceptibility and histogenesis in mice.
The probability that a mouse develops a pulmonary tumor, as well as the structure of that tumor, are dependent on several genes. Three pulmonary adenoma susceptibility (pas) genes predispose some inbred strains to develop lung tumors, even in the absence of carcinogen exposure, and cause others to be resistant. One pas gene is K-ras, which may also be overexpressed in these tumors in a mutated ...
متن کاملDiffusion-weighted imaging of a malignant brenner tumor.
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...
