Abstract

[Invasive ductal carcinoma, not otherwise specified (IDC, NOS), also referred to as invasive breast carcinoma, no special type, (IBC, NST), is the most common invasive carcinoma. It is a diagnosis of exclusion conferred when the tumor cannot be classified as a specific type of breast carcinoma. Consistent with the no special type classification, IDC shows marked heterogeneity in morphology, grade, hormone receptor (HR) and HER2 expression, and prognosis. Invasive tubular and cribriform carcinomas are special types of IBC that are low-grade, invariably HR positive and HER2 negative, and have an excellent prognosis. Microinvasive carcinoma, defined as invasion 1 mm or less in greatest dimension, is usually found in association with carcinoma in situ and shows an overall prognosis similar to ductal carcinoma in situ. Although gene-expression profiling has segregated tumors into different subtypes, classification based on morphologic features is invaluable for some of these special types of breast carcinomas as it determines prognosis and guides treatment options.]
