PRIMARY RENAL LYMPHOMA - A CLINICAL AND RADIOLOGICAL STUDY

Purpose: We assessed the incidence, clinical and radiological features , and prognosis of patients with renal lymphoma. Materials and Methods : We studied 210 patients with symptoms, signs and radiological findin gs suggestive of renal cell carcinoma. Results: Final diagnosis in 6 o f 210 patients (3%) was primary renal lymphoma, Radiological features were similar to those of renal cell carcinoma, Five of the 6 patients had an International Prognostic Index score of greater than 1. Despite appropriate chemotherapy, only 2 patients remain with complete remiss ion. Conclusions: Primary renal lymphoma is unusual but not rare. The relatively poor prognosis in our patients could be attributed to the a dverse prognostic factors associated with aggressive nodal lymphomas.
