title: Lymph node involvement by histiocytosis X.
abstract: Lymph node involvement by histiocytosis X is usually secondary to nearby bone or skin lesions. A patient with histiocytosis X confined to lymph nodes is rarely seen; however, we studied two such persons. In each, a lymph node biopsy was performed because the clinical aspects caused us to suspect neoplastic disease.
