In situ carcinoma In situ carcinomas are malignant epithelial growths that are limited to the acini, terminal ductules, or ductal system of the breast without invasion into the surrounding breast stroma. (25)
1) Ductal carcinoma in situ (DCIS): also known as intraductal carcinoma is considered noninvasive or pre-invasive breast cancer, DCIS means a malignant proliferation of epithelial cells, confined to the lumen of ducts.
In situ carcinomas were divided into three grades: comedocarcinoma has been placed in grade 3. Solid, cribriform and micropapillary carcinomas were designated as grade 1 and classified as grade 2 if they had intermediate cytomorphology. (54)
Comedocarcinoma: is grossly, thick walled ducts filled with
