Macrocyst: as exemplified on this photomicrograph, mitotic activity (arrowheads) is multifocally prominent. The cells lining the ducts and the cysts are cuboidal to low columnar, have indistinct cell borders and a moderate amount of strongly amphophilic cytoplasm that often contains lipid vacuoles. The nucleus tends to be basal, is medium-sized, round to oval and normochromatic. Anisokaryosis and anisocytosis are mild. There is a moderate interstitial granulocytic (eosinophilic?) infiltration. |
