Focusing on tension as a cause of scar keloid in this study, we retrospectively observed the morphology and time sequence changes in scar keloids occuring in various sites of the body surface. The human body surface was divided into 22 regions, and then 160 scar keloids with phymatoid appearances found in 119 patients, who were grouped by their sites using the above mentioned resions, in order to determine the relationship between the site and morphology of keloid. Phymatoid scar keloids could be divided into 3 types: Type I defined as keloids which were markedly protuberant from the surrounding skin and showed dome-like appearances, Type II defined as those which tended to diffuse into the surroundings and showed features of the so-called keloid type, and Type III consisted of those which had a concave region in the center and often showed a tendency toward recovery.
