Tubular. Soft; frequently pedunculated; grayish-white or reddish color; translucent. i. Telangiectatic.

(cancer-nests). Ve els have walls of normal thickne and constitution, and ramify in the stroma, and not among the cells themselves. Three varieties are described histologically: (a) squamous, made up of squamous or flat epithelium; (b) cylindrical, containing columnar cells(c); glandular, composed largely of polyhedral cells, like those of secreting glands. A form of round-celled sarcoma (which see).
