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.
Collins describes a negress of ninety, born of African parents, who exhibited multiple keloids produced by diverse injuries.

At fourteen she was burned over her breasts by running against a shovelful of hot coals, and several months later small tumors appeared, which never suppurated.
