Hypertrophic Scar–Keloid Distinction / 增生性瘢痕与瘢痕疙瘩区分

Definition

The hypertrophic scar–keloid distinction separates raised scar tissue that remains within the original injury and may mature from persistent growth extending beyond the original boundary, often with firmness, color change, itch, pain, or recurrent breakdown.

Current Synthesis

The source treats “scar constitution” as an imprecise public label. Visible or raised scarring after injury does not by itself establish a keloid tendency because ordinary wound healing can pass through a hypertrophic phase. Boundary behavior and time course are more discriminating: hypertrophic scarring remains confined to the injury, while a keloid can grow outward in a claw-like pattern and lacks the same tendency toward spontaneous softening.

Symptoms and history add context. Persistent hardness, red or dark color, itch, pain, growth, ulceration, or drainage support clinical assessment, while familial tendency may be relevant without making heredity a self-diagnostic test. VOL.190 further frames scar behavior as multivariable: body site, movement, tension, contamination, infection, individual biology, and time can all change appearance. Prevention advice, active lesion treatment, and revision of an old scar are different consultation goals.

Key Claims

  • “Scar constitution” should not be inferred from any noticeable scar.
  • Hypertrophic scars remain within the original wound boundary, whereas keloids extend beyond it.
  • Time course and spontaneous maturation help distinguish the processes.
  • Firmness, color, itch, pain, progressive growth, or breakdown can add clinically relevant evidence.
  • Prevention, treatment of active overgrowth, and revision of a mature scar require different plans.
  • Site, mechanical tension, wound condition, aftercare, and maturation time can matter more than a broad self-label of “scar constitution.”

Evidence

Counterevidence & Qualifications

This is a source-scoped recognition framework, not a substitute for examination or pathology when diagnosis is uncertain. Scar behavior varies by site, injury, skin characteristics, tension, inflammation, treatment, and time. The sources do not establish prevalence, inheritance, prevention efficacy, exact intervention windows, or a treatment algorithm.

What Changed

  • Added site, movement, tension, contamination, infection, and maturation time to the classification context.
  • Reinforced that early redness or raised tissue does not by itself establish a permanent keloid tendency.
