Breast cancer types
Cancer type | Histopathology | Image |
---|---|---|
Invasive ductal carcinoma (IDC) | Carcinomatous cells are seen below the basement membrane of lactiferous ducts. Otherwise, there are no specific histologic characteristics, essentially making it a diagnosis of exclusion.[1] | |
Ductal carcinoma in situ (DCIS) | Malignant epithelial cells confined to the ductal system of the breast, without invasion through the basement membrane.[2] | |
Invasive lobular carcinoma (ILC) | The "classic" pattern is round or ovoid cells with little cytoplasm in a single-file infiltrating pattern, sometimes concentrically giving a targetoid pattern. | |
Lobular carcinoma in situ (LCIS) |
Cells have indistinct cell borders, pale cytoplasm, and uniform small nuclei with evenly distributed chromatin and inconspicuous nucleoli.[3] |
|
Mucinous carcinoma | Extracellular mucin areas around tumor cells. | |
Medullary carcinoma | Seemingly fused tumor cells (syncytial pattern), and a prominent lymphoid infiltrate. | |
Solid papillary carcinoma | Larger tumor nests with fibrovascular cores. |
