Pleomorphic lobular carcinoma (PLC) is a rare form of breast cancer and a distinct aggressive subtype of infiltrating lobular carcinoma (ILC). We report on the case of a 68-year-old woman who presented with a mass in her left breast. PLC was diagnosed after excisional biopsy. She then underwent breast-conserving surgery. Immunohistochemically (IHC) the tumor cells were negative for c-erb B2 and progesterone receptor (PgR), but 90% of the cells were positive for estrogen receptor (ER). The tumor was positive for the combined alcian blue/periodic acid Schiff (PAS) stain.
