Infiltrating Lobular Carcinoma

Comments:
Classic or pure invasive lobular carcinoma shows absence of solid, alveolar, papillary, or gland-forming units. The tumor cells are arranged in slender linear strands one to two cells across. In some foci, the so-called Indian file is not conspicuous and the tumor cells may just be dispersed in an irregular fashion in a densely fibrotic stroma.
