Lobular carcinoma in situ and atypical hyperplasias


Lobular carcinoma in situ (LCIS) is a non-invasive multicentric proliferation of atypical epithelial cells in the lobules and terminal ducts of the breast.

Atypical lobular hyperplasia (ALH) describes cells similar to those seen in LCIS that only partially occlude the duct lumen and slightly distend the lobule.
