Pathology Image Detail

Caption

Mammary gland: this is a photomicrograph of the periphery of a "plaque". The tubules at the periphery of the "plaque" are lined by a one cell-thick cuboidal to low columnar epithelium. The cells have indistinct cell borders and a moderate amount of acidophilic cytoplasm. The nucleus is basal, oval, medium-sized, and hyperchromatic. There is no evidence of atypia and mitotic rate is low. The stroma is diffusely infiltrated by a small number of lymphocytes and plasma cells.
