Abortion. The recognition of abortion is usually made by examination of the materialdischarged from the uterine cavity. Usually one finds blood-clots in whichthe villi of the chorion are present. These usually appear as club-shapedmasses with epithelial coverings, showing the characteristic capillary , decidual cells are usually present, and may be recognized by theirlarge size, their round, polygonal, or spindle-shaped form, and their irregularand large nuclei with nucleoli. ^. Fig. 116.—Chorionic villi. {McMurrich.) Vesicular Mole. This condition has been called dropsy of the villi of the chorion, hydatidi-form degeneration of the chorionic villi, cystic mole, and myxoma of the of its most important symptoms is the expulsion through the vagina ofthe vesicles forming the degenerated mass. The mole is a mass of peduncu-lated vesicles which closely resemble a bunch of grapes or gooseberries. Eachvesicle may vary in size from a millet seed to a large hazelnut and containsa fluid which is usually colorless and limpid, but may be reddish and some-what dense. Microscopic examination of the tissue shows the peculiar myxo-matous degeneration of the chorionic Carcinoma. It is not infrequent to observe, in cases of severe hemorrhage throughthe vagina, the appearance of occasional shreds, which on microscopic exami-nation show the charact
