(i.) Adenoma.—By this name are understood tumours whichcopy the type of physiological glandular tissue with a certain degreeof exactitude, but w^ithout assuming its functions. Two groups maybe distinguished amongst them, corresponding to the two principalforms of normal glandular tissue, viz., that of acinous and that oftnhular Fig. 42.—Adeno-myxo-fibro-sarcoma of the Mamma, x 65. (Stained withalum cochineal.) a, Branching fissiire-like glandular cavity ; h, Myxo-fibro-sarcomatous tissue. Although the adenoma imitates the structure of normal glands,there is still no exact correspondence with the latter, certaindivergences existing, partly in the size, partly in the form orarrangement, of the epithelial cells. Adenomata occur not only inglandular organs, but on mucous membranes. Their line of division from the simple glandular hyperplasias is nota sharp one, whilst on the other hand again they may be confoundedwith certain carcinomata, the so-called glandular carcinomata. Asregards the latter, however, the regular arrangement of the epithelialcells, and the sharp delimitation of the adenoma from the tissue in CYSTIC TUMOURS 97 its neighbourhood, form important marks of distinction from car-cinoma. The adenomata are frequently compound tumours (Fig. 41); thatis to say, the accumulation of secretion in them l
