PATHOLOGICAL ANATOMY OF OVAEIAIST CYSTS. 87 The internal structure varies acccording to the number of pocketsand their contents. Cruveilhier divided cysts into unilocular, mul-tilocular, areolar, and compound. This classification need not be re-tained; but for the purposes of description it is well to keep thewords areolar, unilocular, and multilocular. We know that the first-named variety is due to the destructionof intervening walls whose remains are found in the shape of spurs ortrabeculsB. One pocket is usually larger than the others, thoughthere may be several pockets of equal size; by the side of cavities. Fig. 21.—Proligerous Glai^dui,ar Ovarian Cyst of Areolar Appearance. containing several quarts, we find small cysts the size of an orange ora nut. Sometimes a large part of the tumor may be formed by the agglom-eration of very small cavities separated by a more or less dense tissue(occasionally gelatinous) giving the section a honeycombed appear-ance (Fig. 21). In cysts which are considered to be unilocular, andwhich surgically deserve the name, the pathologist will nearly alwaysfind a certain number of secondary cavities in the thickness of thewalls. The cystic pouch can often be separated into three distinct layers,especially near the pedicle; the external layer is fibrous, the middlelayer of connective tissue, the third is formed of a capillary networkcovered by epithelium. The veins, which may be as large as the 88 CLINICAL AISTD OPERATIVE GYNyECOLOGT. femoral or even the vena cava, ramify upon its external surface, andadhere to i
