. Elements of pathological anatomy. Anatomy. 462 UTERUS. [chap. perfect,—a circumstance which, with the dehcacy of their structure, renders them exceedingly Hable to congestion, rup- ture, and hemorrhage. The second species of mole may be called the vascular, (Fig. 94,) in consideration of its structure, which, as the term imports, is essentially of that nature. It is much more rare than the preced- ing, but in what proportion it occurs we have no means to determine. In its shape, the vascular mole is generally globular, and, in its diameter, it varies from one to four inches. Its weight, after the discharge of its contents, ranges from three drachms to one ounce, according to its dimensions, or the thickness of its parietes. In regard to its structure, this variety of mole may be said to bear a striking resemblance to the placenta. Like it, it appears to be essentially composed of blood-vessels, which freely anastomose with each other, and are bound together by delicate, cellular tissue, the whole forming a soft, spongy substance, the thickness of which rarely exceeds the sixth of an inch. In some instances, numerous intersecting filaments may be observed, which are either of a fibrous nature, or obliterated arterial and venous ramifications. Externally, the mole is incrusted with a thin, coriaceous lamella, which is much more delicate than in the fibrinous form: internally, it is furnished with two distinct membranes; the one answer- ing to the chorion, the other to the amnion. They are much more perfectly developed than in the preceding variety, as well as more easily separable from each other ; and the latter always encloses a considerable quantity, occasionally as much as three or four ounces, of watery fluid. Such is a brief account of the two species of uterine moles. The period during which they are retained in the womb is of course liable to some variation, but in the generality of cases it does not exceed three months. In a few instances I have kno
