Langerhans cell histiocytosis (LCH) is a dendritic cell disease. It is classified into two variations: localized or disseminated. Frequency per year is 1 in 200,000 children under 15 years of age. Aggressive forms of the disease are mainly found in younger children. This disease presents oral manifestations, which can sometimes be the first expression of the condition. With relative frequency, jaws can result affected. Radiographic study of the condition shows well circumscribed, osteolytic lesions imparting a pathognomomic ''floating teeth'' image. Patients can be afflicted with lymphadenopathy, fever, irritability, anorexia, pallor, middle ear otitis and anemia. The present article conducts a literature review and presents the case of an 11 month old male infant. This case presents histiocytosis oral expressions, incidence, clinical characteristics, diagnosis and treatment.
