Background: Eosinophilic granuloma (EG), one of the three clinical forms of Langerhans cell histiocytosis (LCH), is a benign inflammatory reaction to an unknown etiologic agent. It most commonly occurs in children and young adults. The most frequently involved bones are the skull, the ribs and the femurs. Alongside the cranium, the maxilla and mandible can also be affected.
Case details: Herein, we report a case of eosinophilic granuloma in a ten years old boy involving posterior quadrants upper and lower jaws as a destructive lesion involving gingiva, periodontium and alveolar bone. Involvement of other bones is ruled out by nucleotide imaging study.
Conclusion: EG should be considered as a differential diagnosis whenever there is a bony destructive lesion involving alveolar bone of the Jaws. Early diagnosis and surgical intervention will resolve the lesion.
