[Serial puncture of lymphnodes. Simultaneous occurrence of chronic lymphatic leukemia and malignant lymphoma with cytologic picture of Hodgkin's disease (author's transl)].

A case of the rare coexistence of chronic lymphatic leukemia and a malignant lymphoma with cytological picture resembling that of Hodgkin's disease is described. The simultaneous occurrence makes the transition from one disease to the other rather doubtful. The author's conclusion is therefore, that it is a coinciding, simultaneous incidence of two different malignant diseases of the lymphatic system. The reader's attention is also drawn to the valuable diagnostic method of serial puncture of lymphnodes.
