Diagnosis of hyperoxalosis on bone marrow aspirate smears.

We present the case of a 29-year-old male from the southern part of India presenting with renal stones, pancytopenia with leukoerythroblastic blood picture, diagnosed on bone marrow (BM) aspiration smears as BM oxalosis. Although it is a rare disorder, BM oxalosis should be considered and BM aspiration and biopsy should be performed in patients presenting with renal stones, pancytopenia with leukoerythroblastic blood picture. Early diagnosis of patients affected by hyperoxaluria is associated with improved long-term survival. [ABSTRACT FROM AUTHOR]
