Galen refers to gynecomastia or gynecomazia; Aristotle says he has seen men with mammae a which were as well developed as those of a woman, and Paulus aegineta recognized the fact in the ancient Greeks. Subsequently Albucasis discusses it in his writings. Bartholinus, Behr, Benedictus, Borellus, Bonet, the Ephemerides, Marcellus Donatus, Schenck, Vesalius, Schacher, Martineau, and Buffon all discuss the anomalous presence of milk in the male breast. Puech says that this condition is found in one out of 13,000 conscripts.
To Bedor, a marine surgeon, we owe the first scientific exposition of this subject, and a little later Villeneuve published his article in the French dictionary. Since then many observations have been made on this subject, and quite recently Laurent has published a most exhaustive treatise upon it.
Robert describes an old man who suckled a child, and Meyer discusses the case of a castrated man who was said to suckle children. It is said that a Bishop of Cork, who gave one-half crown to an old Frenchman of seventy, was rewarded by an exhibition of his breasts, which were larger than the Bishop had ever seen in a woman. Petrequin speaks of a male breast 18 inches long which he amputated, and Laurent gives the photograph of a man whose breasts measured 30 cm. in circumference at the base, and hung like those of a nursing woman.
In some instances whole families with supernumerary breasts are seen. Handyside gives two instances of quadruple breasts in brothers. Blanchard speaks of a father who had a supernumerary nipple on each breast and his seven sons had the same deformities; it was not noticed in the daughters. The youngest son transmitted this anomaly to his four sons. Petrequin describes a man with three mammae, two on the left side, the third being beneath the others. He had three sons with accessory mammae on the right side and two daughters with the same anomaly on the left side. Savitzky reports a case of gynecomazia in a peasant of twenty-one whose father, elder brother, and a cousin were similarly endowed. The patient's breasts were 33 cm. in circumference and 15 cm. from the nipple to the base of the gland; they resembled normal female mammae in all respects. The penis and the other genitalia were normal, but the man had a female voice and absence of facial hair. There was an abundance of subcutaneous fat and a rather broad pelvis.
Wiltshire said that he knew a gynecomast in the person of a distinguished naturalist who since the age of puberty observed activity in his breasts, accompanied with secretion of milky fluid which lasted for a period of six weeks and occurred every spring. This authority also mentions that the French call husbands who have well-developed mammae "la couvade;" the Germans call male supernumerary breasts "bauchwarze," or ventral nipples.
Hutchinson describes several cases of gynecomazia, in which the external genital organs decreased in proportion to the size of the breast and the manners became effeminate. Cameron, quoted by Snedden, speaks of a fellow-student who had a supernumerary nipple, and also says he saw a case in a little boy who had an extra pair of nipples much wider than the ordinary ones. Ansiaux, surgeon of Liege, saw a conscript of thirteen whose left mamma was well developed like that of a woman, and whose nipple was surrounded by a large areola. He said that this breast had always been larger than the other, but since puberty had grown greatly;the genital organs were well formed. Morgan examined a seaman of twenty-one, admitted to the Royal Naval Hospital at Hong Kong, whose right mamma, in size and conformation, had the appearance of the well developed breast of a full-grown woman. It was lobulated and had a large, brown-colored areola; the nipple, however, was of the same size as that on the left breast. The man stated that he first observed the breast to enlarge at sixteen and a half years; since that time it had steadily increased, but there was no milk at any time from the nipple; the external genital organs were well and fully developed. He complained of no pain or uneasiness except when in drilling aloft his breast came in contact with the ropes.
Gruger of St. Petersburg divides gynecomazia into three classes:--(1) That in which the male generative organs are normal;(2) In which they are deformed;
(3) In which the anomaly is spurious, the breast being a mass of fat or a new growth.
The same journal quotes an instance (possibly Morgan's case) in a young man of twenty-one with a deep voice, excellent health, and genitals well developed, and who cohabited with his wife regularly. When sixteen his right breast began to enlarge, a fact that he attributed to the pressure of a rope. Glandular substance could be distinctly felt, but there was no milk-secretion. The left breast was normal. Schuchardt has collected 272 cases of gynecomazia.
