[Malignant lymphoma associated with angioedema]

The incidence of malignant lymphoma cases in constantly growing. Therefore it is worth-while to consider its presence even in cases where the symptoms do not give a clear indication of the disease. Two cases with angiooema being rare and not carachteristic signs for malignant lymphoma are reported. The authors discuss the supposed paraneoplastic patomechanism in malignant lymphoma, i.e. the possible role of C' 1 inhibition. In the view at the cases discussed the authors propose to consider the possible diagnosis of malignant lymphoma if unexplained angiooedema is present.
