Long-standing and unattended hyperoxaluria can progressively impair renal functions, and ultimately lead to renal failure. The devastating phenomenon is characterized by oxalosis, a condition in which calcium oxalate crystals are deposited in the extrarenal organs. [1]The common sites of oxalate deposition are the bones, bone marrow, blood vessels, central nervous system, peripheral nerves, retina, skin, and thyroid, etc. nephrocalcinosis, urolithiasis and progressive renal insufficiency. [3] [2] Calcium oxalate has a very low solubility leading to Here we present a case report of a 29- year old female in whom a diagnosis of oxalosis was made on bone marrow biopsy.
