In order to realize the true nature and stnccture of suck i68 PATHOLOGY AND TREATMENT OF TUMORS. tiunoTs it is absolutely necessary to examine sectiojis from differentparts of the tumor. Some sections from the same specimen will oftenshow epithelial cells almost exclusively, while other sections exhibitonly fibrous tissue. The presence of epithelial cells in different partsof the tumor, however, leaves the impression that they take the essen-tial part in the production of the tumor. Billroth denied that epi-thelial cells took any part in the origin and growth of tumors of thebreast, which he designated as fibroid tumors. The adenoid structureis well marked in the tissues of young tumors, while in old tumorsthe epithelial cells are found arranged in an irregular manner in the.

Figure 8i shows that the connective tissuehas separated the acini, but the glandular appearance is well fibrous tissue is increased by active proliferation of the interacinousconnective tissue, and the new elements impart to the tissues a grayish-red or yellowish color instead of the pearly-white color of old connec-tive tissue. At some points in the older portions of the tumor thefibrous tissue is pale and firm, at othersoedematous or myxomatous. It is a question whether pure fibromataever occur in the mammaiy gland. Un-mixed adenomata are also exceedingly had an opportunity to remove andexamine a pure adenoma of the breast, andhe gives the accompanying illustration () to explain its histological structure.
