A rapid increase in the size of the tumour, together with softening, indicates this change. Cystic --This may result from an extensive mucoid andmyxomatous degeneration, or may he produced as the result of dilatation. Fig. 117.—Uterine Fibkoid with Cystic Degeneration. The tumour is a large interstitial one growing from the posterior wall. In its lowerpart are many spaces filled with clear Huid. * Si » « , ^ \ $ s Fie 118.—Uterine Fibroid—Cystic Degeneration. The cystic character is due partly to a mucoid degeneration and partly to lymphaticdilatation. The dilated lymph spaces with endothelial lining are distinctly seen. 120 GYNECOLOGICAL PATHOLOGY of the lymph channels. The cystic spaces vary in size. When large,they give the tumour a fluctuating character when felt through theabdomen. The formation of these cystic spaces leads to a rapid increasein the size of the growth. When the spaces are formed by dilatation ofthe lymphatics, microscopic examination shows that the lining of thecysts is an endothelium (rig. 118). Sometimes the spaces are filled with blood, and are dilated this the term telangiectatic fibroid has been applied (fig. 119). We
