tions go, the so-called hypertrophy of theprostate is never accompanied by development of adenoma, but only ADENOMATA. 615 by ectasia of the acini and epithelial hyperplasia; the frequently-ob-served enlargement of this gland depends essentially on diffuse ornodular myoma (page 583). The glands of the skin and some mucous membranes may also giverise to development of adenoma and adenosarcoma; it is said thattumors of the skin, which are to be regarded as pure adenomata, mayresult from the glandular epithelium, analogous to the gland-develop-ment in the foetus. Verneuil first described an adenoma of the sweat-glands. I have never observed such tumors, but do not doubt theirexistence, since Rindfleisch has demonstrated to me an adenoma ofthis variety. Those glandular formations that occur in the mucousmembrane of the nose, rectum, and uterus, and which are embeddedin a gelatinous, cedematous connective tissue, more rarely in someother form of sarcoma-tissue, are more frequent.

From a mucous polypus (adenoma) of the rectum of a child. Magnified 60 diameters. Tumors are thus developed which, in general terms, are calledmucous polypi : sometimes they are in broad folds, sometimes nodularpedunculated tumors; they have the color and consistence of themucous membrane whence they spring, are also covered with its epi-thelium, except only the soft polypi of the external auditory meatus; 616 TUMORS. strange to say, these are sometimes covered with ciliated epithelium.All of these mucous polypi do not contain glands; they are usuallyabsent from the aural polypi and the small, leaf-like proliferations ofthe female urethra, the so-called urethral caruncles. The latter neo-plasias consist solely of cedematous and gelatinous connective tissue,with an epithelial covering. Most mucous polypi of the nares, largeintestine, and especially of the rectum, consist to a great extent ofelevated and also newly-formed glands of the mucous membrane,whose closed ends sometimes dilate
