The ear is one of the most common sites of keloid formation, usually associated with the wearing of earrings. However, although this is a small perforating lesion that is equal on both sides, keloids are bigger and more prevalent on the posterior surface. In this study, 141 keloids were evaluated, most of which were located on the posterior surface of the earlobe and caused by the piercing of the ear. Most of the earrings and piercing jewellery used had metallic backs. The more frequent occurrence of earlobe keloids on the posterior surface of the ear therefore may be associated with the exacerbation of local neurogenic inflammation caused by the metallic backs. |
