Eosinophilic granuloma: resolution of lesion after biopsy.

ABSTRACT

Langerhans cell histiocytosis is a collective term used to describe a group of enigmatic proliferative disorders. Three disease variants include eosinophilic granuloma, Letterer-Siwe disease, and Hand-Schuller-Christian syndrome. Eosinophilic granuloma is reported to be the most benign type of the triad. In this report, a 7-year-old child with an eosinophilic granuloma of the left side of her mandible is presented. There was a painless, hard, tender mass arising from the left side of the molar region. Panoramic radiographs showed a radiolucent area at the molar region. The lesion was resolved 2 weeks after the biopsy. The 1.5 years of radiographic and clinical follow-up was satisfactory.
