Sclerotic mandibular bone lesion.

A case of a sclerotic mandibular bone lesion interpreted as a true osteoma has been described, along with the differential diagnosis and treatment. Because the radiographic appearance is not specific for any one lesion, microscopic examination is essential to establish the definitive diagnosis.

Odontogenic myxoma. A clinical and ultrastructural study.

The odontogenic myxoma is an uncommon neoplasm of the jaws that is believed to arise from the primitive, mesenchymal portion of the tooth germ. This study surveys nine cases of odontogenic myxoma of the jaws. Analysis of the clinical material revealed that the myxoma occurred most frequently in the posterior regions of the mandible and will recur if initial therapy is too conservative.
