Chapter IX

.

Albinism is characterized by the absolute or relative absence of pigment of the skin, due to an arrest, insufficiency, or retardation of this pigment. Following Trelat and Guinard, we may divide albinism into two classes,--general and partial.

As to the etiology of albinism, there is no known cause of the complete form. Heredity plays no part in the number of cases investigated by the authors. D'Aube, by his observations on white rabbits, believes that the influence of consanguinity is a marked factor in the production of albinism; there are, however, many instances of heredity in this anomaly on record, and this idea is possibly in harmony with the majority of observers. Geoffroy-Saint-Hilaire has noted that albinism can also be a consequence of a pathologic condition having its origin in adverse surroundings, the circumstances of the parents, such as the want of exercise, nourishment, light, etc.

Lesser knew a family in which six out of seven were albinos, and in some tropical countries, such as Loango, Lower Guinea, it is said to be endemic. It is exceptional for the parents to be affected; but in a case of Schlegel, quoted by Crocker, the grandfather was an albino, and Marey describes the case of the Cape May albinos, in which the mother and father were "fair emblems of the African race," and of their children three were black and three were white, born in the following order: two consecutive black boys, two consecutive white girls, one black girl, one white boy. Sym of Edinburgh relates the history of a family of seven children, who were alternately white and black. All but the seventh were living and in good health and mentally without defect. The parents and other relatives were dark. Figure 73 portrays an albino family by the name of Cavalier who exhibited in Minneapolis in 1887.

Examples of the total absence of pigment occur in all races, but

## particularly is it interesting when seen in negroes who are found

absolutely white but preserving all the characteristics of their race, as, for instance, the kinky, woolly hair, flattened nose, thick lips, etc. Rene Claille, in his "Voyage a Tombouctou," says that he saw a white infant, the offspring of a negro and negress. Its hair was white, its eyes blue, and its lashes flaxen. Its pupils were of a reddish color, and its physiognomy that of a Mandingo. He says such cases are not at all uncommon; they are really negro albinos. Thomas Jefferson, in his "History of Virginia," has an excellent description of these negroes, with their tremulous and weak eyes; he remarks that they freckle easily. Buffon speaks of Ethiops with white twins, and says that albinos are quite common in Africa, being generally of delicate constitution, twinkling eyes, and of a low degree of intelligence; they are despised and ill-treated by the other negroes. Prichard, quoted by Sedgwick, speaks of a case of atavic transmission of albinism through the male line of the negro race. The grandfather and the grandchild were albinos, the father being black. There is a case of a brother and sister who were albinos, the parents being of ordinary color but the grandfather an albino. Coinde, quoted by Sedgwick, speaks of a man who, by two different wives, had three albino children.

A description of the ordinary type of albino would be as follows: The skin and hair are deprived of pigment; the eyebrows and eyelashes are of a brilliant white or are yellowish; the iris and the choroid are nearly or entirely deprived of coloring material, and in looking at the eye we see a roseate zone and the ordinary pink pupil; from absence of pigment they necessarily keep their eyes three-quarters closed, being photophobic to a high degree. They are amblyopic, and this is due

## partially to a high degree of ametropia (caused by crushing of the

eyeball in the endeavor to shut out light) and from retinal exhaustion and nystagmus. Many authors have claimed that they have little intelligence, but this opinion is not true. Ordinarily the reproductive functions are normal, and if we exclude the results of the union of two albinos we may say that these individuals are fecund.

## Partial albinism is seen. The parts most often affected are the

genitals, the hair, the face, the top of the trunk, the nipple, the back of the hands and fingers. Folker reports the history of a case of an albino girl having pink eyes and red hair, the rest of the family having pink eyes and white hair. Partial albinism, necessarily congenital, presenting a piebald appearance, must not be confounded with leukoderma, which is rarely seen in the young and which will be described later.

Albinism is found in the lower animals, and is exemplified ordinarily by rats, mice, crows, robins, etc. In the Zoologic Garden at Baltimore two years ago was a pair of pure albino opossums. The white elephant is celebrated in the religious history of Oriental nations, and is an object of veneration and worship in Siam. White monkeys and white roosters are also worshiped. In the Natural History Museum in London there are stuffed examples of albinism and melanism in the lower animals.

Melanism is an anomaly, the exact contrary of the preceding. It is characterized by the presence in the tissues and skin of an excessive amount of pigment. True total melanism is unknown in man, in whom is only observed partial melanism, characterized simply by a pronounced coloration of part of the integument.

Some curious instances have been related of an infant with a two-colored face, and of others with one side of the face white and the other black; whether they were cases of partial albinism or partial melanism cannot be ascertained from the descriptions.

Such epidermic anomalies as ichthyosis, scleroderma, and molluscum simplex, sometimes appearing shortly after birth, but generally seen later in life, will be spoken of in the chapter on Anomalous Skin Diseases.

Human horns are anomalous outgrowths from the skin and are far more frequent than ordinarily supposed. Nearly all the older writers cite examples. Aldrovandus, Amatus Lusitanus, Boerhaave, Dupre, Schenck, Riverius, Vallisneri, and many others mention horns on the head. In the ancient times horns were symbolic of wisdom and power. Michael Angelo in his famous sculpture of Moses has given the patriarch a pair of horns. Rhodius observed a Benedictine monk who had a pair of horns and who was addicted to rumination. Fabricius saw a man with horns on his head, whose son ruminated; the son considered that by virtue of his ruminating characteristics his father had transmitted to him the peculiar anomaly of the family. Fabricius Hildanus saw a patient with horns all over the body and another with horns on the forehead. Gastaher speaks of a horn from the left temple; Zacutus Lusitanus saw a horn from the heel; Wroe, one of considerable length from the scapula; Cosnard, one from the bregma; the Ephemerides, from the foot; Borellus, from the face and foot, and Ash, horns all over the body. Home, Cooper, and Treves have collected examples of horns, and there is one 11 inches long and 2 1/2 in circumference in a London museum. Lozes collected reports of 71 cases of horns,--37 in females, 31 in males, and three in infants. Of this number, 15 were on the head, eight on the face, 18 on the lower extremities, eight on the trunk, and three on the glans penis. Wilson collected reports of 90 cases,--44 females, 39 males, the sex not being mentioned in the remainder. Of these 48 were on the head, four on the face, four on the nose, 11 on the thigh, three on the leg and foot, six on the back, five on the glans penis, and nine on the trunk. Lebert's collection numbered 109 cases of cutaneous horns. The greater frequency among females is admitted by all authors. Old age is a predisposing cause. Several patients over seventy have been seen and one of ninety-seven.

Instances of cutaneous horns, when seen and reported by the laity, give rise to most amusing exaggerations and descriptions. The following account is given in New South Wales, obviously embellished with apocryphal details by some facetious journalist: The child, five weeks old, was born with hair two inches long all over the body; his features were fiendish and his eyes shone like beads beneath his shaggy brows. He had a tail 18 inches long, horns from the skull, a full set of teeth, and claw-like hands; he snapped like a dog and crawled on all fours, and refused the natural sustenance of a normal child. The mother almost became an imbecile after the birth of the monster. The country people about Bomballa considered this devil-child a punishment for a rebuff that the mother gave to a Jewish peddler selling Crucifixion-pictures. Vexed by his persistence, she said she would sooner have a devil in her house than his picture.

Lamprey has made a minute examination of the much-spoken-of "Horned Men of Africa." He found that this anomaly was caused by a congenital malformation and remarkable development of the infraorbital ridge of the maxillary bone. He described several cases, and through an interpreter found that they were congenital, followed no history of traumatism, caused little inconvenience, and were unassociated with disturbance of the sense of smell. He also learned that the deformity was quite rare in the Cape Coast region, and received no information tending to prove the conjecture that the tribes in West Africa used artificial means to produce the anomaly, although such custom is prevalent among many aborigines.

Probably the most remarkable case of a horn was that of Paul Rodrigues, a Mexican porter, who, from the upper and lateral part of his head, had a horn 14 inches in circumference and divided into three shafts, which he concealed by constantly wearing a peculiarly shaped red cap. There is in Paris a wax model of a horn, eight or nine inches in length, removed from an old woman by the celebrated Souberbielle. Figure 75 is from a wax model supposed to have been taken from life, showing an enormous grayish-black horn proceeding from the forehead. Warren mentions a case under the care of Dubois, in a woman from whose forehead grew a horn six inches in diameter and six inches in height. It was hard at the summit and had a fetid odor. In 1696 there was an old woman in France who constantly shed long horns from her forehead, one of which was presented to the King. Bartholinus mentions a horn 12 inches long. Voigte cites the case of an old woman who had a horn branching into three portions, coming from her forehead. Sands speaks of a woman who had a horn 6 3/4 inches long, growing from her head. There is an account of the extirpation of a horn nearly ten inches in length from the forehead of a woman of eighty-two. Bejau describes a woman of forty from whom he excised an excrescence resembling a ram's horn, growing from the left parietal region. It curved forward and nearly reached the corresponding tuberosity. It was eight cm. long, two cm. broad at the base, and 1 1/2 cm. at the apex, and was quite mobile. It began to grow at the age of eleven and had constantly increased. Vidal presented before the Academie de Medecine in 1886 a twisted horn from the head of a woman. This excrescence was ten inches long, and at the time of presentation reproduction of it was taking place in the woman. Figure 76 shows a case of ichthyosis cornea pictured in the Lancet, 1850.

There was a woman of seventy-five, living near York, who had a horny growth from the face which she broke off and which began to reproduce, the illustration representing the growth during twelve months. Lall mentions a horn from the cheek; Gregory reports one that measured 7 1/2 inches long that was removed from the temple of a woman in Edinburgh; Chariere of Barnstaple saw a horn that measured seven inches growing from the nape of a woman's neck; Kameya Iwa speaks of a dermal horn of the auricle; Saxton of New York has excised several horns from the tympanic membrane of the ear; Noyes speaks of one from the eyelid; Bigelow mentions one from the chin; Minot speaks of a horn from the lower lip, and Doran of one from the neck.

Gould cites the instance of a horn growing from an epitheliomatous penis. The patient was fifty-two years of age and the victim of congenital phimosis. He was circumcised four years previously, and shortly after the wound healed there appeared a small wart, followed by a horn about the size of a marble. Jewett speaks of a penile horn 3 1/2 inches long and 3 3/4 inches in diameter; Pick mentions one 2 1/2 inches long. There is an account of a Russian peasant boy who had a horn on his penis from his earliest childhood. Johnson mentions a case of a horn from the scrotum, which was of sebaceous origin and was subsequently supplanted by an epithelioma.

Ash reported the case of a girl named Annie Jackson, living in Waterford, Ireland, who had horny excrescences from her joints, arms, axillae, nipples, ears, and forehead. Locke speaks of a boy at the Hopital de la Charite in Paris, who had horny excrescences four inches long and 11 inches in circumference growing from his fingers and toes.

Wagstaffe presents a horn which grew from the middle of the leg six inches below the knee in a woman of eighty. It was a flattened spiral of more than two turns, and during forty years' growth had reached the length of 14.3 inches. Its height was 3.8 inches, its skin-attachment 1.5 inches in diameter, and it ended in a blunt extremity of 0.5 inch in diameter. Stephens mentions a dermal horn on the buttocks at the seat of a carcinomatous cicatrix. Harris and Domonceau speak of horns from the leg. Cruveilhier saw a Mexican Indian who had a horn four inches long and eight inches in circumference growing from the left lumbar region. It had been sawed off twice by the patient's son and was finally extirpated by Faget. The length of the pieces was 12 inches. Bellamy saw a horn on the clitoris about the size of a tiger's claw in a its origin from beneath the preputium clitoridis.

Horns are generally solitary but cases of multiple formation are known Lewin and Heller record a syphilitic case with eight cutaneous horns on the palms and soles. A female patient of Manzuroff had as many as 185 horns.

Pancoast reports the case of a man whose nose, cheeks, forehead, and lips were covered with horny growths, which had apparently undergone epitheliomatous degeneration. The patient was a sea-captain of seventy-eight, and had been exposed to the winds all his life. He had suffered three attacks of erysipelas from prolonged exposure. When he consulted Pancoast the horns had nearly all fallen off and were brought to the physician for inspection; and the photograph was taken after the patient had tied the horns in situ on his face.

Anomalies of the Hair.--Congenital alopecia is quite rare, and it is seldom that we see instances of individuals who have been totally destitute of hair from birth. Danz knew of two adult sons of a Jewish family who never had hair or teeth. Sedgwick quotes the case of a man of fifty-eight who ever since birth was totally devoid of hair and in whom sensible perspiration and tears were absent. A cousin on his mother's side, born a year before him, had precisely the same peculiarity. Buffon says that the Turks and some other people practised depilatory customs by the aid of ointments and pomades, principally about the genitals. Atkinson exhibited in Philadelphia a man of forty who never had any distinct growth of hair since birth, was edentulous, and destitute of the sense of smell and almost of that of taste. He had no apparent perspiration, and when working actively he was obliged to wet his clothes in order to moderate the heat of his body. He could sleep in wet clothes in a damp cellar without catching cold. There was some hair in the axillae and on the pubes, but only the slightest down on the scalp, and even that was absent on the skin. His maternal grandmother and uncle were similarly affected; he was the youngest of 21 children, had never been sick, and though not able to chew food in the ordinary manner, he had never suffered from dyspepsia in any form. He was married and had eight children. Of these, two girls lacked a number of teeth, but had the ordinary quantity of hair. Hill speaks of an aboriginal man in Queensland who was entirely devoid of hair on the head, face, and every part of the body. He had a sister, since dead, who was similarly hairless. Hill mentions the accounts given of another black tribe, about 500 miles west of Brisbane, that contained hairless members. This is very strange, as the Australian aboriginals are a very hairy race of people.

Hutchinson mentions a boy of three and a half in whom there was congenital absence of hair and an atrophic condition of the skin and appendages. His mother was bald from the age of six, after alopecia areata. Schede reports two cases of congenitally bald children of a peasant woman (a boy of thirteen and a girl of six months). They had both been born quite bald, and had remained so. In addition there were neither eyebrows nor eyelashes and nowhere a trace of lanugo. The children were otherwise healthy and well formed. The parents and brothers were healthy and possessed a full growth of hair. Thurman reports a case of a man of fifty-eight, who was almost devoid of hair all his life and possessed only four teeth. His skin was very delicate and there was absence of sensible perspiration and tears. The skin was peculiar in thinness, softness, and absence of pigmentation. The hair on the crown of the head and back was very fine, short, and soft, and not more in quantity than that of an infant of three months. There was a similar peculiarity in his cousin-german. Williams mentions the case of a young lady of fifteen with scarcely any hair on the eyebrows or head and no eyelashes. She was edentulous and had never sensibly perspired. She improved under tonic treatment.

Rayer quotes the case of Beauvais, who was a patient in the Hopital de la Charite in 1827. The skin of this man's cranium was apparently completely naked, although in examining it narrowly it was found to be beset with a quantity of very white and silky hair, similar to the down that covers the scalp of infants; here and there on the temples there were a few black specks, occasioned by the stumps of several hairs which the patient had shaved off. The eyebrows were merely indicated by a few fine and very short hairs; the free edges of the eyelids were without cilia, but the bulb of each of these was indicated by a small, whitish point. The beard was so thin and weak that Beauvais clipped it off only every three weeks. A few straggling hairs were observed on the breast and pubic region, as in young people on the approach of puberty. There was scarcely any under the axillae. It was rather more abundant on the inner parts of the legs. The voice was like that of a full-grown and well-constituted man. Beauvais was of an amorous disposition and had had syphilis twice. His mother and both sisters had good heads of hair, but his father presented the same defects as Beauvais.

Instances are on record of women devoid of hair about the genital region. Riolan says that he examined the body of a female libertine who was totally hairless from the umbilical region down.

Congenital alopecia is seen in animals. There is a species of dog, a native of China but now bred in Mexico and in the United States, which is distinguished for its congenital alopecia. The same fact has been observed occasionally in horses, cattle, and dogs. Heusner has seen a pigeon destitute of feathers, and which engendered a female which in her turn transmitted the same characteristic to two of her young.

Sexualism and Hair Growth.--The growth or development of the hair may be accelerated by the state of the organs of generation. This is peculiarly noticeable in the pubic hairs and the beard, and is fully exemplified in the section on precocious development (
