title: Histiocytosis X Langerhans cells react with antiinterleukin-2 receptor monoclonal antibody.
abstract: Immunohistochemical study of 7 cases of histiocytosis X (HX) and of histologically normal skin shows that HX Langerhans cells react with Bl.49.9 monoclonal antibody which recognizes the Interleukin-2 receptor, whereas normal skin Langerhans cells do not. This reactivity suggest activation of HX Langerhans cells.
