Breast Pathology
Breast pathologyBreast pathology
The normal microscopic appearance of female breast tissue is shown here. There is a larger duct to the right and lobules to the left. A collagenous stroma extends between the structures. A variable amount of adipose tissue can be admixed with these elements.
Here is the microscopic appearance of a fibroadenoma. To the right is compressed breast connective tissue forming a "capsule" to this mass. The neoplasm itself is composed of a fibroblastic stroma in which are located
elongated compressed ducts lined by benign appearing epithelium.

intraductal carcinoma
The cells in the center of the ducts with comedocarcinoma are often necrotic and calcify, as shown here. This central necrosis leads to the gross characteristic of extrusion of cheesy material from the ducts with pressure (comedone-like).
