Pathology Image Detail

Caption

Fibroadenoma with atypia: the neoplasm is composed of dilated glands filled with a proteinaceous material and embedded in a large amount of dense fibrovascular stroma. There are two layers to the neoplastic epithelium: (1) a luminal layer composed of cuboidal cells that often contain lipid vacuoles and occasionally proteinaceous droplets; (2) an inconspicuous basal (=myoepithelial) layer. There is no evidence of atypia in this microscopic field.
