because , depending on their state of activation and/or differentiation , langerhans cells exhibit a varying immunophenotype , we investigated whether histiocytosis x cells display a similar phenotypic heterogeneity and , if so , whether the heterogenous biological behavior of histiocytosis x is reflected by differences in the immunophenotype of the proliferating cells .
