[Histopathology of Kaposi's sarcoma]

After reviewing the histo-pathological characteristics of Kaposi's sarcoma, the authors show particular patterns of this disease in equatorial Africa (especially Cameroon). They note 3 associations with lymphomas, with special emphasis on 13 new observations of general lymph node enlargement in children. For 2 of these cases, remissions were observed. Finally, they stress the lack of information on the histogenesis with the mysterious links between lymphocytes and Kaposi's sarcoma.
