title: Ultrastructural features of human lymphomas.
abstract: The diagnostic value of some ultrastructural details in a series of 73 lymphomas, 7 thymomas, 6 cases of Waldenström's disease, and 5 myelomas has been critically reviewed. The light microscopical diagnoses of "reticulum cell sarcoma" seems now inadvisable, since thhe majority of these cases, when examined by electron microscopy, were found to be "blast cell sarcomas", probably lymphoid in nature. Clear-cut relationships between cell ultrastructure and immunfluorescence data about surface Ig in lymphoid cell populations have not been ascertained.
