Primary Acinic Cell Carcinoma of the Breast: A Clinicopathological and Immunohistochemical Study
Figure 4
Microscopic findings showed that the tumor had an infiltrative growth pattern with a combination of solid (a), trabecular, and microglandular (b) features. Many of the tumor cells had clear cytoplasm containing large, coarse, and bright red granules which resemble acinar cells of the salivary glands (c). Immunohistochemical staining showed that most of the tumor cells stained strongly for amylase (d), lysozyme (e), and α1ACT (f).
