Three cases of non‐Hodgkin's lymphoma, B‐cell type, identical histologically to so called neoplastic angioendotheliosis (NAE), are reported. All showed a rapidly progressive clinical course and were not properly diagnosed before death. The lymphoma cells were distributed in many vessels of systemic organs with a tendency to form aggregates. The primary sites in the three cases were probably the adrenal gland, lymph node, and spleen, respectively. In particular, in one case it was suggested that the lymphoma cells had spread from the adrenal tumor to other organs, showing the histological features of NAE. In the literature, the primary sites of NAE have been scarcely mentioned. However, gross tumors were present in some cases. In such cases, it is possible that the tumors could be the primary sites of NAE. We conclude that some non Hodg‐kin's lymphomas can exhibit the features of NAE during their course, particularly in the terminal stages. Acta Pathol Jpn 42: 272‐278, 1992.
