    Tlie acinous variety consists of acini, lined with spheroidal epithehum, and comnuinicating with each other by duct- like channels. The acini are clustered in twos, threes,_ or more, and are separated and bound together by connective tissue, in which the vessels ramify. Pure adenomata are rare, the scanty amount of intertubular and interacinous connective tissue in such being more of ten _ replaced by fibrous tissue {adeno-fihroma), or by mucous tissue {adeno- myxoma), or by sarcomatous elements {adeno-sarcoma), or by a combination of two or more of the above tissues (adeno-fibro-sarcoma, adeno-inyxo-sarcoma); whilst at tinies the acini or ducts become dilated into cysts, in which Fig. 10.—Adenomatous Tumour. ]nolifcrating growths {iniracystic groivtlts) may j)roject. ITie tumour is then spoken of as an adeno-cystoma, ajsto- ■■iuraiina, &c., according to the character of the intertubular and interacinous connective tissue. The microscopical appearance of an adenoma is shown in Fig. 10. The tubular adenomata resemble the tubular glands; they are most common in the mucous membrane of the intestine, whore they form papillary or polypoid growths. Both varieties are distinguished from carcinoma, in that the epithelium does not peneti-ate the basement membrane and invade the coinicctivo tissue. Umud seats.—The acinous occur in the mamma, where they are generally of the adcno-fibromatous form, the lip, the prostate, the thyroid, parotid, and lachrymal glands, and the sebaceous glands of the skin. The tubular occur in the intestine, es]>ecially the rectum.
