About 100 illustrative cases of malignant lymphoma and non-tumorous lymph node processes studied by electron microscopy were revised. Some distinguishing features were stressed as about nuclear patterns and intercellular relations of basic lymphatic elements. The centrocyte is unique in a fine chromatin pattern of the cleft nuclei and in varied superficial qualities. It tends to form junctions with dendritic cells and bilateral dense bodies remaining from severed cellular projections. The centroblast and immunoblast represent a different structural line related to plasmacytes and macrophages or epitheloid cells. The T-line tends to form characteristic junctions with interdigitating cells as well as dense invaginations of cytoplasmic membrane on the both sides of junctions. There is a limited number of similar junctions with pericytes. Dense bodies produced at the junction of lymphatic and stromal reticular cells are discussed.
