title: Multiple skin tumors of indeterminate cells in an adult.
abstract: An adult patient with multiple unusual histiocytic tumors of the skin is described. As shown by immunohistologic study, electron microscopy, and immunoelectron microscopy, the tumors represent circumscribed proliferations of the Langerhans cell-related indeterminate dendritic cells of the skin. This distinct cutaneous histiocytosis may represent a paraneoplastic syndrome.
