Cysto-sarcoma proliferum, give an illustration which corresponds tol-erably well to the above. A second case belonging here I have alreadydescribed under tubular cysto-adenoma of the mamma {ArcMv. Cldrurgic, Bd. I, p. C49). In this case there was as much difficultyin the clinical as in the anatomical diagnosis. I here quote from myformer description: A short time ago (July, 18G5) I extirpated a tumor from the rightbreast of a young married woman of about 24 years of age, who had neverbeen pregnant; the tumor was about the size of a hens q^^, was immov- TUMOKS OF THE MAMMARY GLAIS^D. 83 able in the gland, felt lobular and uneven, and caused moderate painswhich radiated to the arm of the affected side; it had developed in thecourse of one year.
