    Hypertrophic Scars and Keloids

    Two patterns of abnormal wound healing

    • Three ways a wound can heal
    • Normal wound healing has three phases
    • Fetal skin heals without scarring
    • Differences in adult versus fetal wound healing.
    • Who develops hypertrophic scars and keloids
    • Risk factors for abnormal scarring
    • Genetic syndromes linked to keloids
    • Chemical messengers that drive scarring
    • TGF-beta isoforms play opposite roles
    • How a keloid differs from a hypertrophic scar
    • Keloids on the trunk, neck, and shoulder
    • How fast do these scars appear and change
    • A hypertrophic scar after a knife injury
    • Comparing the three scar types side by side
    • Clinical features of conventional scars, hypertrophic scars, and keloids.
    • Scoring a scar objectively
    • Vancouver Scar Scale.
    • What the pathologist looks for
    • Hypertrophic scar under the microscope
    • Keloid under the microscope
    • Histologic features side by side
    • Staining tests do not fully separate the two
    • Further hypertrophic scar histology
    • Other diseases that look like a keloid
    • Nodular morphea mimicking a keloid
    • Tumors that look like a scar under the microscope
    • Keloids without an obvious cause
    • Multiple keloids from acne
    • Extensive spontaneous keloids
    • Claw-like keloid of the flexor arm
    • Keloid at an earlobe piercing site
    • Treatment starts with prevention
    • First-line injected and topical treatments
    • Other injectable options
    • Evidence-based treatment options
    • Surgical and physical treatments
    • Pulsed dye laser before and after treatment

    • How the contracture develops
    • Variable finger involvement
    • Complications of longstanding disease
    • What the tissue looks like under the microscope
    • Conditions that can mimic Dupuytren disease

    Hyaline Fibromatosis Syndrome

    A rare genetic disorder with glassy skin nodules

    • One gene, two severities
    • First described 150 years ago
    • How the mutation causes fibrosis
    • Where the nodules appear
    • Clinical features of hyaline fibromatosis syndrome.
    • Clinical features of hyaline fibromatosis syndrome. (continued)
    • What the biopsy shows

    Elastic Tissue-Related Disorders

    When elastic fibers, not collagen, build up in the skin
