    [From The Johns Hopkins Hospital Bulletin, No. 18, December, 1891.] /C4 / ' •• ~; i CONTRIBUTIONS TO THE HISTOGENESIS OF THE PAPILLARY CYSTOMATA OF THE OVARY, (From the Pathological Laboratory of the Johns Hopkins University and Hospital.) matous cystomata have been recognized as constituting a class of tumors perfectly distinct from the ordinary glandular cystomata; for previous to the year 1877 when Olshausen13 first demonstrated this fact the two forms of growths were considered as one, or at most subdivisions of the same class of tumors, and consequently as derived from the same source. This fact must be borne in mind in considering all the early work done upon this subject. Although the ordinary ovarian cystoma had been known for a great length of time as ovarian dropsy, it was not until 1829 that Hodgkin 1 pointed out the existence of papillary growths upon the interior of the cyst. He ascribed their formation to pressure, and it will perhaps be interesting to quote his words describing the process. “ I have stated that it is at particular points on the in- terior surface of the superior cyst that clusters of inferior cysts take their origin. It sometimes happens that the number of cysts forming the clusters is so great in proportion to the space which they occupy that, like trees too thickly planted, they interfere with each other’s growth. Their development is more or less limited to an increase of dimension in length. Yet as their free extremities are allowed to diverge, we sometimes find the slender peduncle gradually dilating into a pyriform cyst. At other times the dilatation does not take place till near the extremity of the peduncle, and then produces a cyst more nearly resembling a grape or a currant. At other times no dilatation takes place, probably from the cavities having been wholly obliterated. The pedunculated cysts or the extreme of this variety in the form of filaments are either produced singly, but in the closest approxi- mation from a particular spot of the containing cyst, or they may By J.
