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. ^[1]

The nuclei are arranged in a disorganized manner.^[2] This is in contrast to a Langhans giant cell, where the nuclei are arranged on the border.
