ABSTRACT

A 44-year-old woman was referred to our hospital because of a suspected left mandibular cyst. Panoramic radiography revealed three ill-defined unilocular radiolucent lesions in the mandible and maxilla. Ml three biopsies were not revealed to the cyst wall, however cemento-osseous dysplasia was diagnosed at only one lesion. After surgical curettage, panoramic radiography demonstrated bone regeneration at the sites of both lesions. One year 2 months later, a new lesion was detected in the mandible, but a biopsy showed that it lacked a cyst wall. These findings indicated that this patient had very rare multiple simple bone cysts of the mandible and maxilla. Key words: simple bone cyst, multiple osseous dysplasia, mandible, maxilla, cemento.
