IPLab:Lab 7:Fibroadenoma

Clinical Summary

Four months prior to admission, this 25-year-old female became aware of a lump beneath the areola of her right breast. Physical examination confirmed the presence of an approximately 3 cm movable, rubbery mass. An aspiration was attempted but did not yield any fluid or cells. At the time of surgical exploration, a well-circumscribed mass was identified and removed.

This low-power photomicrograph of the surgical specimen demonstrates two ovoid, well-circumscribed nodules surrounded by fibroadipose tissue.
In this higher magnification you can see the solid parenchyma with numerous variable sized glandular spaces.

The ducts are lined by two cell layers, one of cuboidal, two columnar cells (inner layer) and an outer layer of flattened cells with hyperchromatic nuclei (myoepithelial cells).
