title: [Mastoid osteomas: review of literature and presentation of 2 clinical cases].
abstract: The authors report two cases of mastoid osteoma in patients at the "S. Filippo Neri" Hospital in Rome, Italy. The literature on this topic is critically reviewed. This review includes the 48 cases between 1875 and 1955 reported by Kecht, as well as the 92 cases Probst reported in 1991 in a review running from 1861. The literature published since 1991 has presented eight cases which, when added to the two presented here and the 92 indicated by Probst, total 102 cases of mastoid osteoma. The most widely accepted theories on the etiopathogenesis of mastoid osteoma are presented. These include: embryogenesis, metaplasia, inflammation, and trauma. The conclusions underline the complications of this disorder which are mainly linked to osteoma growth, and the importance of the differential diagnosis with other mastoid lesions for which prognosis is poorer.
