[Problems diagnosing cat scratch disease].

The diagnosis of cat scratch disease is hampered by the fact the basic laboratory investigations fail to demonstrate characteristic changes of this disease, and the diagnosis is based usually on epidemiological history and the clinical symptom complex. The diagnosis is confirmed by the complement binging test with the antigen obtained from pathologically changed lymph nodes with values over 1.5 being pathognomonic for the disease, and by the cutaneous tests of Hanger-Rose and Mollaret. The authors present 2 cases treated for the disease stressing differences in its course.
