Keloids and Hypertrophie Scars

Abnormal skin scarring was first described in the Smith papyrus between 2500 and 3000 BC [7]. In 1817, Alibert proposed the word “cheloide” (keloid) to differentiate these lesions from malignant neoplasms [2]. Today, keloids and hypertrophie scars are recognized as uncontrolled proliferations of fibrous tissue after injury or trauma to the skin [15]. However, meanwhile hypertrophie scars are confined to the extent of the original wound; in contrast, keloids invade the surrounding skin [15].
