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. Thetubules were lined by at twenty strataof epithelial cells. The writer removed a tumor the size of ahazelnut from the breast of a young lady, and from its firmness. Fig. 82.—Pure adenoma of themammary gland (after Haeckel).(Zeiss, Obj. D., Oc. 2.) ADENOMA. 169 was led to believe the tumor to be a fibroma. The macroscopicalappearance of a section of the tumor showed wavy bundles of connec-tive tissue, thus confirming the opinion formed. Under the microscopethe tumor revealed itself as a genuine adenoma. The microscopic ap-pearance of the tumor-tissue and the relative proportion of glandularand connective tissue are shown in the accompanying illustration (). It will be seen from this illustration that, although the tumor hadexisted for several years, the tubules are Hned by a number of layersof epithelial cells and that the glandular spaces are small.
