When the fibrons stroma is small in amount and the cells areswollen and predominant, the tumor is called encephaloid (Fig. 176);when they are hard and dry, it is called scirrhus (Fig. 168).. Fig. 173.—Carcinoma, or Atypical Epithelioma. Section of one of the nodules of Fig. 168. On themedian edge of the section the pavement epithelium ceases and is replaced by an erosion presentinga structure almost papillary and more or less ramified glands. The stroma is formed of fibrous bandswhich divide the aveoli of different sizes and these again are subdivided by smaller bands. The aveoliare filled with polymorphic cell elements; the exact origin of the cell-nests is difficult to determine; theyare apparently from glandular cavities, of which some are covered with a single layer of cylindricalepithelium. These cavities are transformed to solid cords by the proliferation of the cells; the normalglands can be followed from the surface up to the middle of the cancerous nodule (Wyder).
