In this particu- Fig. Colloid cancer of tlie ovary. (After Cruveilhier.) lar respect colloid cancer appears to stand between the various cystic diseases already described, and those forms of cancer which are not colloid, in the position of one of those " esculent groups" which have been some- times employed in classifications of the animal kingdom as connecting links, to bring into juxtaposition objects which, though exhibit- ing certain near affinities, could not be in- cluded in one common group, without violence to the principles upon which a natural ar- rangement should be based. Not, however, to enter further upon the disputed question of the nature of alveolar cancer of the ovary, it will suffice to notice those peculiarities which are generally to be observed when the disease affects that org;in. Since colloid cancer of the ovary does not generally destroy life until the disease has made great progress, the specimens of ovaries so af- fected which come under our notice are often of large size, filling the pelvis and abdomen, and equalling in bulk the masses of cyst formation of a more innocent type. Such a mass, when incised, may be found to include the entire ovarian structure, which is converted into a collection of cysts, or alveolar cavities, varying greatly in size and in the thickness of their walls. Such a variety is often seen in dif- ferent portions of the same structure. The surface of a section may p
