[Inguinal swelling and ankle edema after inguinal hernia operation].

We diagnosed an aggressive Non-Hodgkin-Lymphoma (diffuse large B-cell lymphoma, DLBCL) in a patient with a fast growing inguinal mass. Only one third of all suspicious inguinal lymph nodes that are investigated histologically are found to be malignant lymphoma. If so, an accurate histopathological evaluation of sufficient neoplastic tissue is critical. Prognosis in DLBCL is highly associated with the IPI score. Overall survival has been improved by the CHOP-R regimen established in 2002, with a disease-free survival exceeding 50%.
