The mean echogenicity was defined as the sum of the product of each intensity level (varying from 0–63) and the number of pixels for that intensity concentration divided by the total number of pixels in the measured area, as follows: This grouping of an oocyte and its supporting cells is called a follicle. The great majority of Krukenberg tumors are signet-ring cell carcinomas arising in the stomach. Atretic Follicles; Corpora lutea Cortex. This avascular area is useful to the surgeon in isolating the adnexal … Tumors of this type are also called ovarian adenocarcinoma.

See the above photomicrograph. The stroma of the ovary is a unique type of connective tissue abundantly supplied with blood vessels, consisting for the most part of spindle-shaped stroma cells. Cells from nearby intraabdominal locations can attach to the ovary, causing the ovarian stroma and other ovarian tissues to interact with these new cells causing cellular growth and metastasis (Danhausen et al., 2019). Ovarian tumors can arise from the migration of cells from mesoderm originating tissues to the surface of the ovary (Danhausen et al., 2019). Ovarian Stroma- Ovarian stroma is the soft connective tissue with a huge supply of blood. Serum CA-125 is often … The stoma cells are distributed in such a way that the tissue appears to be whorled.
