The Indeterminate Cell Proliferative Disorder: Report of a Case Manifesting as an Unusual Cutaneous Histiocytosis

Abstract
A patient with an unusual, distinctive cutaneous histiocytosis is described. Extensive morphologic, antigenic, and enzymatic studies indicate that this histiocytosis represents a proliferative disorder of cutaneous indeterminate cells. Features that distinguish this disorder from other histiocytoses are discussed.
