Triad of benign ovarian tumor with ascites and pleural effusion that resolves after resection of the tumor. PATHOLOGY OF OVARIAN TUMORS. The stroma may be fibrous or resemble ovarian stroma. A rare, benign, ovarian tumor which is probably of stromal origin and characterized by a distinctive microcystic appearance. Consider the causes of this pathology, diagnostic methods, types of treatment and prevention. Serum CA-125 is often elevated but is only 50% accurate so it is not a useful tumour marker to assess the progress of treatment. Ovarian stroma is composed of densely packed spindle cells resembling fibroblasts and is divided into cortex and medulla. THE OVARY. 1)—according to the anatomic structures from which the tumors presumably originate. Ovarian fibromas constitute the majority of … The major genetic risk factor for ovarian cancer is a mutation in BRCA1 or BRCA2 genes, or in DNA mismatch repair genes, which is present in 10% of ovarian cancer cases. Because of cyst rupture and mucin extravasation, large areas of necrosis accompanied by histiocytes and inflammatory cells may be present ( Fig. In some instances, it may contain smooth muscle, luteinized cells ( Fig. Ovarian hyperplasia is a gynecological disease characterized by the proliferation of stroma and endometrium, which leads to an increase in the ovary. A gene mutation that occurs spontaneously in the body tissues or in the cancer cells that cannot be passed on to offspring (i.e., it cannot be inherited). 3 x 1.5 cm long and 1 cm thick. People with hereditary nonpolyposis colon cancer (Lynch syndrome), and those with BRCA-1 and BRCA-2 genetic abnormalities are at increased risk..
