What delayed reaction manifests as small, raised, tender bumps post-coral scrape?

Answer

Granulomas

A significant complication of coral scrapes involves delayed reactions caused by microscopic debris remaining embedded in the skin after the initial injury. If small fragments of the calcareous coral material or associated proteins are left behind, the body recognizes them as foreign substances and initiates a defense mechanism. This reaction manifests as granulomas, which are described as small, raised, tender bumps that can be intensely itchy. These bumps often persist for several weeks or even months as the body attempts to wall off and eliminate the trapped foreign material. This process is termed a foreign body reaction and distinguishes coral injuries from typical terrestrial cuts.
