[A case report of pseudolymphoma of the kidney and orbit].
Pseudolymphoma is reactive extranodal lymphocytosis, and it's lymphocytes are so minimally atypical that it is basically benign. The patient was a 68-year-old female with pain in the left back and lower abdomen. Plain CT (computerized tomogram) of the kidney revealed a mass in the left kidney. It had a smooth surface and higher density than parenchyma. Similarly a left orbital mass was revealed by CT. We could not deny the mass to be a malignant tumor, so we took specimens from these lesions by an open biopsy. Histological examination of these specimens showed pseudolymphoma. Pseudolymphoma of the left kidney was reduced in its size by treatment with prednisolone. The patient is continuously followed up to date.
