The difference between a keloid and a granuloma lies mainly in their cause and appearance. Keloids are overgrowths of scar tissue that form at the site of a healed skin injury, extending beyond the injury site. They are often shiny and raised. Granulomas, on the other hand, are small areas of inflammation caused by infection or an inflammatory condition, not necessarily related to an external skin injury. They may look like a small nodule or bump under the skin.
