In describing adenomas and cysts of the breast, it waspointed out that a galactophorous duct not infrequently dilatesand forms a cyst of some size, and occasionally the terminal duct 303 304 EPITHELIAL TUM0UB8 by whicli it opens on the nipple becomes patent and allows thepent-iip fluid to escape from time to time. The close relationof these cysts to the nipple, and the possibility of obtainingfluid by gentle pressure, are valuable diagnostic signs. The epithelial processes or warts that may sprout fromsome part of the cyst-wall of these cysts are occasionally so.

The warty growths insuch cysts may be firm and not bleed; in others, when theyare very vascular, they resemble in colour and shape a ripemulberry, projecting into the cyst. Rarely they sprout soluxuriantly as to fill the cyst with delicate papillomatousprocesses like the villous papilloma so common in theurinary bladder.
