Nucleated Red Blood, teaching point, arkana laboratories
The patient is a 70-year-old male who presents with a creatinine of 5 mg/dl and a history of primary myelofibrosis. The biopsy shows a kidney with severe glomerular and tubulointerstitial chronicity, approaching end-stage kidney disease from arterionephrosclerosis. Interestingly, circulating nucleated red blood cells were identified in the arteries and peritubular capillaries. Although not representing a specific kidney disease, the presence of nucleated red blood cells within the circulation points toward premature release of erythroid precursors from the bone marrow. This finding is has been reported in the setting of a space-occupying lesion in the bone marrow from metastases or in...

Disease Week: Onco-Nephrology

Onco-Nephrology, disease week, arkana laboratories, renal pathology
Monday Onco-nephrology is a rapidly developing area of nephrology designed to help address and prevent kidney problems and the many complex issues that arise in cancer patients. AKI is a common complication in cancer patients. The highest 1-year risk of AKI was seen in patients with kidney cancer (44%), liver cancer (33%), and multiple myeloma (31.8%) in one large population-based cohort study. Patients with distant metastases were at highest risk. https://www.ncbi.nlm.nih.gov/pubmed/21767759 What is the most common glomerular pathology reported in patients with solid tumors? Minimal change disease Membranoproliferative glomerulonephritis Membranous nephropathy Thrombotic microangiopathy   Answer: Membranous nephropathy.  The incidence of cancer was significantly higher in patients with...
