reviously, 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.
