PRIMARY RENAL NON-HODGKINS LYMPHOMA PRESENTING: DISCUSSION
Primary renal lymphoma (PRL), describes non-Hodgkin’s lymphoma involving the kidney in the absence of any other organ or nodal disease focus. The majority of patients are older than 40 years and present with acute renal failure. Flank pain, hematuria, weight loss, and abdominal mass are other common manifestations, similar to renal cell carcinoma. PRL presenting with immune thrombocytopenia has also been reported. Lymphoid tissue is normally absent in renal histological architecture and consequently the existence of PRL has been questioned.
