B-CELL NON-HODGKINS-LYMPHOMA PRESENTING AS A PRIMARY RENAL TUMOR IN ACHILD

A 6-year-old boy presented with a unilateral renal tumour thought to b e a Wilms' tumour. He had started a treatment but review of the histol ogy and immunohistochemical studies proved the tumour to be a primary renal B-cell lymphoma. This case illustrates the importance of an open -minded approach in the histological examination of small round cell t umours in the kidney and immunohistochemical studies in such cases are strongly advocated.
