Patient: A bag grew on the ear where the auricle was pierced in the past, slowly growing from a small size to the size of a soybean grain. The time started in October 07. I want to see how to treat it? Doctor’s answer: This is a keloid tumor, or keloid, formed by piercing the ear hole; it is related to the keloid body, the stimulation of bad metal components in the earring studs and repeated local infections. Do not squeeze to stimulate it, it may grow bigger and bigger; the only effective way is to remove it surgically, others like local injection of hormone, paste scar paste etc. have some auxiliary effect.
