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 cov
