Ziemssen figures an interesting case of naevus pilosus resembling "bathing tights". There were also present several benign tumors (fibroma molluscum) and numerous smaller nevi over the body. Schulz first observed the patient in 1878. This individual's name was Blake, and he stated that he was born with a large naevus spreading over the upper parts of the thighs and lower parts of the trunk, like bathing-tights, and resembling the pelt of an animal. The same was true of the small hairy parts and the larger and smaller tumors. Subsequently the altered portions of the skin had gradually become somewhat larger. The skin of the large hairy naevus, as well as that of the smaller ones, was stated by Schulz to have been in the main thickened, in part uneven, verrucose, from very light to intensely dark brown in color; the consistency of the larger mammiform and smaller tumors soft, doughy, and elastic. The case was really one of large congenital naevus pilosus and fibroma molluscum combined.
A Peruvian boy was shown at the Westminster Aquarium with a dark, hairy mole situated in the lower part of the trunk and on the thighs in the position of bathing tights. Nevins Hyde records two similar cases with dermatolytic growths. A sister of the Peruvian boy referred to had a still larger growth, extending from the nucha all over the back. Both she and her brother had hundreds of smaller hairy growths of all sizes scattered irregularly over the face, trunk, and limbs. According to Crocker, a still more extraordinary case, with extensive dermatolytic growths all over the back and nevi of all sizes elsewhere, is described and engraved in "Lavater's Physiognomy," 1848. Baker describes an operation in which a large mole occupying half the forehead was removed by the knife.
In some instances the hair and beard is of an enormous length. Erasmus Wilson of London saw a female of thirty-eight, whose hair measured 1.65 meters long. Leonard of Philadelphia speaks of a man in the interior of this country whose beard trailed on the ground when he stood upright, and measured 2.24 meters long. Not long ago there appeared the famous so-called "Seven Sutherland Sisters," whose hair touched the ground, and with whom nearly every one is familiar through a hair tonic which they extensively advertised. In Nature, January 9, 1892, is an account of a Percheron horse whose mane measured 13 feet and whose tail measured almost ten feet, probably the greatest example of excessive mane development on record. Figure 88 represents Miss Owens, an exhibitionist, whose hair measured eight feet three inches. In Leslie's Weekly, January 2, 1896, there is a portrait of an old negress named Nancy Garrison whose woolly hair was equally as long.
The Ephemerides contains the account of a woman who had hair from the mons veneris which hung to the knees; it was affected with plica polonica, as was also the other hair of the body.
Rayer saw a Piedmontese of twenty-eight, with an athletic build, who had but little beard or hair on the trunk, but whose scalp was covered with a most extraordinary crop. It was extremely fine and silky, was artificially frizzled, dark brown in color, and formed a mass nearly five feet in circumference.
Certain pathologic conditions may give rise to accidental growths of hair. Boyer was accustomed to quote in his lectures the case of a man who, having an inflamed tumor in the thigh, perceived this part becoming covered in a short time with numerous long hairs. Rayer speaks of several instances of this kind. In one the part affected by a blister in a child of two became covered with hair. Another instance was that of a student of medicine, who after bathing in the sea for a length of time, and exposing himself to the hot sun, became affected with coppery patches, from which there sprang a growth of hair. Bricheteau, quoted by the same authority, speaks of a woman of twenty-four, having white skin and hair of deep black, who after a long illness occasioned by an affection analogous to marasmus became covered, especially on the back, breast, and abdomen, with a multitude of small elevations similar to those which appear on exposure to cold. These little elevations became brownish at the end of a few days, and short, fair, silky hair was observed on the summit of each, which grew so rapidly that the whole surface of the body with the exception of the hands and face became velvety. The hair thus evolved was afterward thrown out spontaneously and was not afterward reproduced.
Anomalies of the Color of the Hair.—New-born infants sometimes have tufts of hair on their heads which are perfectly white in color. Schenck speaks of a young man whose beard from its first appearance grew white. Young men from eighteen to twenty occasionally become gray; and according to Rayer, paroxysms of rage, unexpected and unwelcome news, diseases of the scalp such as favus, wounds of the head, habitual headache, over-indulgence of the sexual appetite, mercurial courses too frequently repeated, too great anxiety, etc., have been known to blanch the hair prematurely.
The well-accepted fact of the sudden changing of the color of the hair from violent emotions or other causes has always excited great interest, and many ingenious explanations have been devised to account for it. There is a record in the time of Charles V of a young man who was committed to prison in 1546 for seducing his girl companion, and while there was in great fear and grief, expecting a death-sentence from the Emperor the next day. When brought before his judge, his face was wan and pale and his hair and beard gray, the change having taken place in the night. His beard was filthy with drivel, and the Emperor, moved by his pitiful condition, pardoned him. There was a clergyman of Nottingham whose daughter at the age of thirteen experienced a change from jet-blackness of the hair to white in a single night, but this was confined to a spot on the back of the head 1 1/2 inches in length. Her hair soon became striped, and in seven years was totally white. The same article speaks of a girl in Bedfordshire, Maria Seeley, aged eight, whose face was swarthy, and whose hair was long and dark on one side and light and short on the other. One side of her body was also brown, while the other side was light and fair. She was seen by the faculty in London, but no cause could be established.
Voigtel mentions the occurrence of canities almost suddenly. Bichat had a personal acquaintance whose hair became almost entirely gray in consequence of some distressing news that reached him. Cassan records a similar case. According to Rayer, a woman by the name of Perat, summoned before the Chamber of Peers to give evidence in the trial of the assassin Louvel, was so much affected that her hair became entirely white in a single night Byron makes mention of this peculiar anomaly in the opening stanzas of the "Prisoner of Chillon:"—
"My hair is gray, but not with years, Nor grew it white In a single night. As men's have grown from sudden fears."
