Foreign-body giant cell

A foreign-body giant cell is a collection of fused macrophages (giant cell) which are generated in response to the presence of a large foreign body. This is particularly evident with implants that cause the body chronic inflammation and foreign body response. This reaction to the implant causes damages to the infected area, leaving the exterior surface with scars.Foreign-body giant cell reaction to a suture.

A foreign-body giant cell is a collection of fused macrophages (giant cell) which are generated in response to the presence of a large foreign body. This is particularly evident with implants that cause the body chronic inflammation and foreign body response. This reaction to the implant causes damages to the infected area, leaving the exterior surface with scars. The nuclei are arranged in a disorganized manner. The nuclei in this cell are centrally placed and overlap each other. This is in contrast to a Langhans giant cell, where the nuclei are arranged on the border. Foreign body cells can detect and eliminatebacteria caught within the body, by sensing the unique sugar coating that areon the invading prokaryotes. These macrophage cells are one of a fewphagocytic cells, but not the first to come to an injury site, and tend tolinger from anytime between days to weeks. There has been some research done on other variations ofgiant cells with different functions.
