keloid

Full Definition

An abnormal proliferative scar that extends beyond the boundaries of the original injury and does not regress spontaneously. Keloids are more common in darker-skinned individuals and certain anatomical locations such as the chest, shoulders, and earlobes. In burn patients, keloids can develop months to years after healing and may cause functional impairment and cosmetic concerns. Treatment is challenging and may include steroid injections, radiation, or surgical excision combined with adjuvant therapy.

Usage

Usage note: Distinguish from hypertrophic scar, which remains within original wound boundaries.
