Intralesional Treatment for Keloids and Hypertrophic Scars: A Review

BackgroundAlthough differing in clinical presentation and prognosis, keloids and hypertrophic scars are generally characterized by abnormally proliferative scar tissue and are extremely debilitating. Several intralesional therapies have been studied in attempts to find a universally safe and effective modality, of which there are currently none. ObjectiveTo provide a comprehensive review of current intralesional treatment modalities for keloids and hypertrophic scars. Methods and MaterialsA PubMed search was performed for literature pertaining to intralesional treatment modalities for keloids and hypertrophic scars. References from retrieved articles were also considered for review. Results and ConclusionMany intralesional therapies for keloids and hypertrophic scars are currently available to physicians and patients. Mechanisms of action and side effect profiles vary between these agents, and new approaches to keloids and hypertrophic scars are frequently being explored. Randomized controlled trials are needed to assess these new and promising modalities fully.
