Nodular pedunculated keloid on the posterior earlobe, common with ear piercing.

A keloid is a firm red to purple nodule with telangiectasia that extends beyond the area of trauma.

A keloid formed after an injury. The lesions were injected with triamcinolone 10 mg/cc at intervals of weeks. Early lesions respond better to treatment than older lesions do.

Hypertrophic scars and keloids can arise at any skin site. Most occur on the chest, hand, neck and earlobe. Occasionally, keloids arise spontaneously, without any preceding trauma.
