Hypertrophies of the Breast.—CongenitalHypertrophy.—At birth the structure and generalcharacters of the mammarj- glands are apparentlyidentical in the two sexes, at which stage of growththey are composed of ducts and acini, some welldeveloped and others imperfectly so, enclosed in aloose fatty connective tissue. But commencing im-mediately after birth the breasts assume rapid devel-opmental changes and cell proliferation in the ducts,which sometimes exceeds the normal limits and pro-duces an overgrowth of the gland, accompanied bythe secretion of a mUk-like fluid similar to condition is known as congenital or infantile hyper-trophy, and is not infrequenth found in connectionwithVprecocious development of the sexual organs inyoung infants. It has been suggested that this con-dition is similar to the early sexual developmentoccurring in female children in tropical Fig. 1111.—Precocious Development of the Breast in a ChildFour Years and Nine Months Old. Menstruation began at theage-of fifteen months. (Mudd, Am. Practice of Surgery.) Physiological Hypertrophy.—This type of hy-pertrophy represents the natural enlargement of themammary gland associated with certain changes in-cident to pubescence. LntU the period of pubertyis attained there is no perceptible difference in thestructure of the male and the female mUk-gland, butat this time further development in the male ceases,whereas in the female breast renewed evolutionarychanges begin and progress until the menstrual func-tion is fully established. After this period the mam-mary changes again remain in abeyance untilstimulated to renewed activity bj gestation, atwhich time marked hypertrophy takes place and 464 steadily goes on to the time of lactation, when theg
