Background
Keloid and hypertrophic scars are benign and fibrotic
proliferations which demonstrate abnormal wound-
healing responses in susceptible individuals [1]. Scar
hypertrophy following midline sternotomy for cardiac
surgery is rare, occurring more in pigmented skin. It is
estimated that up to 4.5% of the general population suffer from hypertrophic scarring [2]. We describe a
patient of fair complexion who developed a thick keloid
scar at the sites of sternotomy, chest drains and temporary pacing wire.
