Langerhans cell histiocytosis presenting as bilateral eosinophilic granulomata in the molar region of the mandible. A case report.

Eosinophilic granuloma represents one of a triad of lesions encompassing a disease under the generic name, histiocytosis X or Langerhans cell histiocytosis. Localised eosinophilic granuloma, multifocal eosinophilic granuloma, Hand-Schüller-Christian disease, and the most malignant form of histiocytosis, Letterer-Siwe disease, can all present as destructive bony lesions of the jaws. The present case was a 30-year-old man who presented with almost total destruction of the periodontal support to the left and right mandibular, 1st and 2nd molars. Whereas the radiographic features were typical of eosinophilic granuloma, the clinical appearance and mirror image presentation were unusual.
