title: Mandibular histiocytosis X and acute lymphoblastic leukemia.
abstract: The occurrence together of two major distinct diseases in the oral area is relatively rare. In this report, a case is presented in which histiocytosis X was found to develop in a child with acute lymphoblastic leukemia. The nature of the differentiated histiocytoses is explored, and the possibility of the relationship between a lymphoproliferative and a histiocytic disease entity is investigated.
