Rosette-like arrays of highly birefringent calcium oxalate crystals are commonly seen in the marrow space of bone biopsy specimens taken from patients with primary hyperoxaluria, particularly if complicated by renal failure. Similar deposits have been described in chronic hemodialysis patients with secondary forms of oxalosis. Large multinucleated histiocytes may be seen surrounding these crystal deposits. Many of these cells are histologically indistinguishable from osteoclasts. We present a patient in whom this histiocytic reaction appeared to be of sufficient magnitude to stimulate bone resorption and to cause severe osteodystrophy. This observation, and those of other investigators reviewed in the discussion, suggest that oxalate deposition within bone may contribute to the pathogenesis of uremic osteodystrophy in chronic renal failure patients with primary or secondary types of oxalosis. |
