title: Intracellular Ig identification on paraffin-embedded solitary plasmacytoid proliferation: a routine method to define the biological nature of plasma cells.
abstract: The difficulty to recognize morphologically the biological nature of the exuberant plasma cell proliferations is known by every pathologist. Therefore, an immunohistochemical method has been applied to routine paraffin-embedded sections of biopsies from 26 patients suspected to bear a solitary plasmacytoma. The method has allowed to distinguish between monoclonal (likely to be neoplastic) and polyclonal cases (likely to be reactive).
