Membranous Nephropathy and Intrarenal Extramedullary Hematopoiesis in a Patient With Myelofibrosis

Kidney disease in the setting of a hematologic malignancy is common, with the frequency and type of kidney disease varying depending on the specific malignancy. Various glomerular diseases and tumor infiltration of the kidneys have been reported in patients with lymphoproliferative disorders. Descriptions of kidney involvement in myeloproliferative disorders have been much rarer. We report a case of membranous nephropathy accompanied by kidney injury in a patient with primary myelofibrosis with additional features considered related to the patient's myeloproliferative disorder.
