This photomicrograph shows the compressed connective tissue (arrow) between two nodules of dense fibrous tissue and ducts.
File:IPLab7Fibroadenoma3.jpg
This is a higher magnification of the fibroadenoma showing the dense stroma of the tumor surrounding the irregularly shaped ducts. The adjacent fibrofatty tissue containing breast ducts and lobules has been compressed by the tumor.
File:IPLab7Fibroadenoma2.jpg
This is a higher magnification of one of the three nodules. At this power, the nodule seems to be composed of a solid parenchyma with small glandular spaces. The adjacent breast parenchyma consists mostly of fat.
