Giant cell from a bronchial wash. Pap stain.

Giant cells are "big" cells with multiple nuclei. They come in different flavours, which are suggestive of causality.

This article deals with the classic types of giant cells. A more general differential diagnosis of giant cells is in giant cell lesions.

Giant cell types

List:

  • Touton giant cell.
  • Osteoclast-like giant cell.
  • Foreign body type giant cell.
