title: Giant cell tumor compression of the deep branch of the ulnar nerve.
abstract: A case of giant cell tumor compression of the ulnar nerve at the loge de Guyon is noted. Due to great variation of the anatomy of the deep branch, plus the varying locations of lesion appearance, numerous presentations of the ulnar tunnel syndrome are manifested. When recognized, early surgery and complete decompression are in order.
