Ewing`s sarcoma of the mandible misdiagnosed as periodontal inflammation: Report of three cases

摘要

Ewing`s sarcoma (ES) is the second most common childhood primary malignant tumor of the bone. The most popular locations of ES are long bones and pelvis. The involvement of the mandible is very rare in childhood. In last 10 years, we met with three cases of ES of the mandible in our department. Initially the patients had symptoms similar to periodontal inflammation. The involvement of the mandible might be considered with periodontal inflammation in its initial stages, what frequently leads to delayed treatment. Although this tumor has an aggressive clinical behavior and rapid growth, early diagnosis can reduce patient`s morbidity and mortality and thus it is important to distinguish from periodontal inflammation.
