Primary hyperoxaluria is a rare autosomal recessive disorder resulting in diffuse deposition of insoluble oxalate crystals in multiple organs. Two-thirds of patients have nephrolithiasis by 5 years of age and 80% die of renal failure by 20 years of age. Rarely, the disease will present in adulthood, with the onset of symptoms occurring as late as the sixth decade. Oxalosis is a condition in which the highly insoluble calcium oxalate crystals are deposited in extrarenal tissue. Pathologic involvement of bone is recognized as osteosclerosis on radiograph. Oxalosis should be considered in patients with osteosclerotic bone changes and chronic renal failure and should not be misinterpreted as renal osteodystrophy. We describe here a case of oxalosis in a 33-year-old man.
