Bullough lesions, or Bullough's bumps, are protuberant fibro-osseous lesions of the temporal bone, involving the external mastoid surface.
Only a handful of case reports are available since it was first described in 1999 1-4.
These lesions feature a bland fibrous stroma with interspersed foci of ossification 1,2.
