Tympanosclerosis and concentric lamellated bodies in middle ear.

In a case of bilateral tympanosclerosis, in addition to the tympanosclerotic changes, the round (or ovoid) concentric lamellated bodies in the right tympanic cavity (epitympanum and mesotympanum) and mastoid cavity were found. The pathogenesis of tympanosclerosis was discussed in conjunction with those concentric lamellated bodies including its relationship with Pacinian body or middle ear corpuscle.
