Anomalies and Curiosities of Medicine [173]
of the generative apparatus to be discussed, although not distinctly belonging under this head, will be those of the mammae.
Amazia, or complete absence of the breast, is seldom seen. Pilcher describes an individual who passed for a female, but who was really a male, in whom the breasts were absolutely wanting. Foerster, Froriep, and Ried cite instances associated with thoracic malformation. Greenhow reports a case in which the mammae were absent, although there were depressed rudimentary nipples and areolae. There were no ovaries and the uterus was congenitally imperfect.
There was a negress spoken of in 1842 in whom the right breast was missing, and there are cases of but one breast, mentioned by King, Paull, and others. Scanzoni has observed absence of the left mamma with absence of the left ovary.
Micromazia is not so rare, and is generally seen in females with associate genital troubles. Excessive development of the mammae, generally being a pathologic phenomenon, will be mentioned in another chapter. However, among some of the indigenous negroes the female breasts are naturally very large and pendulous. This is well shown in Figure 144, which represents a woman of the Bushman tribe nursing an infant. The breasts are sufficiently pendulous and loose to be easily thrown over the shoulder.
Polymazia is of much more frequent occurrence than is supposed. Julia, the mother of Alexander Severus, was surnamed "Mammea" because she had supernumerary breasts. Anne Boleyn, the unfortunate wife of Henry VIII of England, was reputed to have had six toes, six fingers, and three breasts. Lynceus says that in his time there existed a Roman woman with four mammae, very beautiful in contour, arranged in two lines, regularly, one above the other, and all giving milk in abundance. Rubens has pictured a woman with four breasts; the painting may be seen in the Louvre in Paris.
There was a young and wealthy heiress who addressed herself to the ancient faculty at Tubingen, asking, as she displayed four mammary, whether, should she marry, she would have three or four children at a birth. This was a belief with which some of her elder matron friends had inspired her, and which she held as a hindrance to marriage.
Leichtenstern, who has collected 70 cases of polymazia in females and 22 in males, thinks that accessory breasts or nipples are due to atavism, and that our most remote inferiorly organized ancestors had many breasts, but that by constantly bearing but one child, from being polymastic, females have gradually become bimastic. Some of the older philosophers contended that by the presence of two breasts woman was originally intended to bear two children.
Hirst says: "Supernumerary breasts and nipples are more common than is generally supposed. Bruce found 60 instances in 3956 persons examined (1.56 per cent). Leichtenstern places the frequency at one in 500. Both observers declare that men present the anomaly about twice as frequently as women. It is impossible to account for the accessory glands on the theory of reversion, as they occur with no regularity in situation, but may develop at odd places on the body. The most frequent position is on the pectoral surface below the true mammae and somewhat nearer the middle line, but an accessory gland has been observed on the left shoulder over the prominence of the deltoid, on the abdominal surface below the costal cartilages, above the umbilicus, in the axilla, in the groin, on the dorsal surface, on the labium majus, and on the outer aspect of the left thigh. Ahlfeld explains the presence of mammae on odd parts of the body by the theory that portions of the embryonal material entering into the composition of the mammary gland are carried to and implanted upon any portion of the exterior of the body by means of the amnion."
Possibly the greatest number of accessory mammae reported is that of Neugebauer in 1886, who found ten in one person. Peuch in 1876 collected 77 cases, and since then Hamy, Quinqusud, Whiteford, Engstrom, and Mitchell Bruce have collected cases.
