Pathology Image Detail
Caption |
Mammary gland: this photomicrograph focuses on the alveoli of a mammary lobule affected by ductal carcinoma in situ. There is moderate anisokaryosis. In contrast to the ducts where mitotic figures were prominent, mitoses are not found in the alveoli. |

Ductal carcinoma in situ, with sclerosis, mammary gland |

Notes |
These lesions are very unique and are difficult to categorize. As indicated by the MMHCC panel of pathologists, these lesions have similarities with the human entity known as "sclerosing adenosis". However, they also differ from sclerosing adenosis of man in that the mitotic rate is higher, cells lining the ducts pile-up disorderly, there is squamous differentiation, and atypia is more prominent. |
