title: [Sarcoma arising from Langerhans cellsĭ].
abstract: A rare case of tumor arising from Langerhans cells in the tongue and neck area in a 37 year-old man is presented. It was a polymorphocellular sarcoma with bean-like twisted nuclei. Electron microscopy identified granules of Langerhans (Bierbeck), multiple tubulo-vesicular structures, ring-like plates, Golgi apparatus, lysosomes and dendritic processes. Total leukocytic antigen was assayed in tumor cells but no expression of S-100 protein found.
