A rare case of primary otoscleroma of the middle ear.

OBJECTIVE

We report an extremely rare case of primary otoscleroma.

METHOD: We present a case report and a review of the world literature concerning otoscleroma.

RESULTS

An adult woman presented with chronic suppurative otitis media with tubotympanic disease and conductive hearing loss. On mastoid exploration, dark granulations were seen, which were identified as otoscleroma on histopathological examination. The patient responded well to streptomycin.

CONCLUSION

To the best of our knowledge, this is the first report of primary otoscleroma in the world literature. This case indicates that Frisch's bacillus can also spread to the middle ear.
