He said that it had
always been as long as this, but had lately become thicker, and
two months previously the skin over the lower part of the tumor
had ulcerated. This large tumor was successfully removed; it
consisted of fibrous tissue, with large veins running in its
substance. The excised mass weighed 51 pounds. The patient made
an early recovery.
Keloids are fibromata of the true skin, which may develop
spontaneously or in a scar. Although the distinction of true and
false keloid has been made, it is generally discarded. According
to Hebra a true typical keloid is found once in every 2000 cases
of skin-disease. It is, however, particularly the false keloid,
or keloid arising from cicatrices, with which we have mostly to
deal. This tumor may arise from a scar in any portion of the
body, and at any age. There seems to be a disposition in certain
families and individuals to keloid-formations, and among negroes
keloids are quite common, and often of remarkable size and
conformation. The form of injury causing the cicatrix is no
factor in the production of keloid, the sting of an insect, the
prick of a needle, and even the wearing of ear-rings having been
frequent causes of keloid-formations among the negro race.
