Autosomal dominant osteopetrosis and maxillomandibular osteomyelitis

Osteopetroses represent a heterogeneous group of rare, hereditary bony dysplasias. They range from a devastating neurometabolic disease (including severe malignant infantile osteopetrosis) to 2 more benign conditions principally affecting adults: autosomal dominant osteopetrosis (ADO) type I and type II. The present study describes the maxillofacial manifestations associated with the 2 subgroups of ADO. In this paper, we present the oldest patient described in the literature with ADO type I (76 years old). We also document the first ADO type II patient described in the literature with synchronic osteomyelitis of the mandible and the maxilla. (c) 2005 Elsevier Inc. All rights reserved.
