The pedicle of a submucous fibroid may become sufficientlyelongated to allow the tumour to pass through the cervicalcanal into the vagina, and even protrude at the vulva. Whenthis happens an interesting change takes place in the epithelium UTERINE FIBROIDS m of the protruded part. So long as the tumour is containedwithin the cavity of the uterus, the epitheUum covering it isindistinguishable from that lining the cavity of the the tumour enters the vagina, the columnar epitheliumstratifies on the protruded surface, but that lining the glandularrecesses remains columnar and retains its cilia (Fig. 91). 3.

When the number is limitedto three or four, one or more of them may attain moderateproportions; like the submucous variety, they often becomepedunculated, and when numerous they cause the uterus toassume a characteristic tuberous appearance. Sometimesas many as fifteen or twenty of these protuberances may becounted on a uterus, and they vary in size from a pea to alarge walnut. In such cases, even when no intramural tu-mours are present, the walls of the uterus are thicker thannatural.
