Is diffuse sclerosing osteomyelitis of the mandible part of the synovitis, acne, pustulosis, hyperostosis, osteitis (SAPHO) syndrome? Analysis of seven cases

Diffuse sclerosing osteomyelitis of the mandible has been described as a localized disease of unknown origin. We offer evidence that mandibular involvement in the recently described synovitis acne pustulosis hyperostosis osteitis syndrome exactly fits the accepted description for diffuse sclerosing osteomyelitis of the mandible. The clinical, radiologic, and pathologic findings in seven such cases are presented and discussed.
