Histiocytose langerhansienne mandibulaire

Langerhan's cell histiocytosis is a rare disease. The mandibular location has variable clinical expressions which can vary from dental mobility to tumor development in the gingiva. The radiological appearance is also variable; histological proof is required for diagnosis. Treatment depends on the number and locations of the lesions. In case of a single location, the treatment options may vary from a “wait and see” attitude to a non aggressive surgery, with a possible local corticosteroid therapy or radiothe-rapy. For multiples locations, chemotherapy is indicated.
