Dermal Hypertrophies
Hypertrophic Scar
• Firm, initially pink to purple in color then becomes skin-colored to hypopigmented, occasionally hyperpigmented; papule or plaque limited to an excision site or wound (Figs. 81.1 and 81.2).

• Most commonly seen on the trunk/shoulders.
• With treatment, can reduce pruritus and height but not width of scar.
Keloid
• More common in patients with darkly pigmented skin who have a familial predisposition.
• Rarely associated with syndromes (e.g. Rubinstein–Taybi or Goeminne syndromes).
• Raised, often skin-colored firm plaque(s) that, in contrast to hypertrophic scars, extend beyond the wound margin (Fig. 81.3; Table 81.1); color may vary as in hypertrophic scars.
