As a result of pressure exerted 011 it by a surroundingnormal uterine musculature, it was gradually expelled into the uterinecavity. The fact that the tumor filled the cervical canal can be ex-plained by the previous filling of the upper uterine cavity by the dis-crete submucous myomatous nodule in this location. The adenomyo-matous growth in its earlier stage must have been very similar to thecase of Cullens, the illustrations of which I have taken the libertyto insert in my paper. (Fig. 9.) Therefore, the source of the glandelements in my tumor were, originally, from the endometrium and,accordingly are of Muellerian origin. The question might be raised: Why do not all of these glands havethe pattern of the endometrium? We note that, in some instances,around both small and dilated glands there is an absence of the endo-.

The structure of the tumor is also well seen in thispicture. metrium-like stroma. On the other hand, this endometrium-like stromasurrounds in varying degrees all sorts of glands, both large and small,throughout the tumor, being more marked in the base of the tumorand in that portion immediately adjoining the base. On account ofthe marked pressure which has been exerted on the tumor by the sur-rounding uterine Avail, and on account of pressure which has resultedin consequence of the marked gland dilatation, this stroma tissuecould readily have become obliterated. It is also quite justifiable toassume that the gland tubules could have penetrated the muscularmatrix of themselves, the stroma being held on account of the in-creasing pressure. So f
