[Primary renal lymphoma].
OBJECTIVE
To describe a case of primary renal lymphoma.


METHODS
We presents a patient with a right renal mass which histological analysis revealed a non-Hodgkin Lymphoma.


RESULTS
A 78-year-old male patient with right flank pain mass was referred to our Service. He was diagnosed of renal mass by imaging studies. Inmunohistochemical investigations revealed a B-cell-type lymphoma. He received combination chemotherapy with CHOP.


CONCLUSIONS
Primary renal lymphoma is a rare disease whose existence has been questioned, because the kidney does not normally contain lymphoid tissue. Its clinical presentation is like any other renal tumor and its definitive diagnosis is by histology. Elective treatment is chemotherapy (CHOP).
