Breast, Invasive ductal carcinoma, HER2 stain [LMP86629]
Keywords
invasive ductal carcinoma, tubular features, breast, Nottingham grade I/III
Clinical History
Right breast lumpectomy in a 50-year old patient who noticed skin dimpling. Speculated mass on mammography.
Clinical Discussion
This is an example of invasive ductal carcinoma (IDC) with prominent tubular features (Nottingham grade I/III). While this may be an added qualifier appropriate in the microscopic description, it is important to distinguish this entity from "tubular carcinoma". While numerous tubular structures are present, "tubular carcinoma" is a low-grade tumour, associated with better prognosis and Rosen’s triad (combination of columnar cell hyperplasia, lobular carcinoma in situ and tubular carcinoma).
