Invasive lobular carcinoma of breast

Description

An infiltrating lobular adenocarcinoma. The malignant cells lack cohesion and are arranged individually or in a linear manner (Indian files), or as narrow trabeculae within the stroma. The malignant cells are usually smaller than those of ductal carcinoma, are less pleomorphic, and have fewer mitotic figures.
