The ear lobe is a common site for keloid formation. A history of ear piercing is found in most cases of earlobe keloids.
We analyzed 58 patients with unilateral keloid resulting from bilateral ear piercing to examine a potential relationship between methods of piercing, inflammation, infection or any symptoms after piercing and keloid formation.
There was no correlation between keloid formation and the physician who performed the piercing or methods by which the piercing was done. However, a correlation was found with perforation becoming infected or inflamed for long periods.
Some patient had removed the pierce because of inflammation at the site of earlobe piercing, after with the keloid formation began. It was suggested that if there is inflammation or infection at the earlobe after piercing, the patient should visit the clinic for consultation before removing the pierce.
