Intracanalicular adenocarcinoma.—This tumor grows as finger-like branching and anastomosing strands of epithelial tumor cells extending into a loose stroma (Fig. 99A). The edges of these strands are smooth due to an orderly paHsade arrangement of a single outer layer of epithelial cells. Within this palisade layer the entire remainder of these finger-like processes is composed of epithelial tumor cells of the same type and size but with a disorderly arrangement due to loss of normal orientation (Fig. 99B). These tumor cells are closely packed and cuboidal in shape, somewhat larger than normal resting mammar}^ gland epithelium, with moderately.
