title: Histiocytosis X of the nose.
abstract: A case of histiocytosis X of the nose in a 5-year-old Nigerian child has been described. This localization of the lesion with secondary involvement of the submandibular cervical nodes is quite unusual and no similar case has been so far reported in the literature. The difficulties encountered in the diagnosis, the aetiological factors and treatment are briefly discussed.
