Primary intracranial histiocytic lymphoma with Langerhans' granules. A light microscopic and ultrastructural study.
An intracranial tumor classified as a histiocytic lymphoma was studied with light and electron microscopic examination and immunocytochemical methods. The characteristics of the malignant mononuclear phagocyte cells are described. The presence of some cells containing Langerhans' granules suggests differentiation towards a specialized cell of the mononuclear phagocyte system: the Langerhans' cell.
