A possible case of primary renal lymphoma: a case report.
BACKGROUND
The entity primary renal lymphoma is controversial and rare.


METHODS
We report a case in a 60-year-old man. Computed tomography revealed a large, homogeneous, retroperitoneal mass with 14.8 x 11.5 cm size arising from the right kidney. An ultrasound guided percutaneous biopsy was performed and the tumour was diagnosed histopathological as non-Hodgkin lymphoma. The patient was treated by systemic chemotherapy and thereafter a nephrectomy was performed.


CONCLUSIONS
Primary renal lymphoma is a controversial and infrequent disease. However, there is growing evidence that it does exist.
