Pathological microscopic examination. (a) Clusters of malignant epithelial cells infiltrate the uterine fibroma. Staining: hematoxylin and eosin. Top left: magnified image of fibroid cells; bottom left: magnified image of carcinoma cells. (b) Immunohistochemical staining positive for gross cystic disease fluid protein-15 (GCDFP-15) and mammaglobin. (c) Hematoxylin and eosin staining of the primary breast cancer specimen demonstrates poor epithelial staining of the malignant cells with irregular nuclei. ILC, invasive lobular carcinoma.
