Oral manifestations of oxalosis secondary to ileojejunal intestinal bypass

Oxalosis is a rare condition that may be either hereditary or acquired. It may be secondary to a number of primary causes, which include renal failure, oxalate poisoning, malabsorption syndromes, and in this case, ileojejunal bypass surgery. Systemic oxalate overload following such bypass surgery results from a defect in the enterohepatic circulation and from the loss of calcium and bile salts in the feces. The oxalate is then absorbed into the circulation, and the supersaturated solution precipitates in the systemic tissues. Reported cases of oral involvement are rare. This article presents a 2 1/2-year follow-up of such a patient and the resultant progressive and unrelenting nature of the disorder. As a result of our experience, we suggest early aggressive oral surgical management of the widespread oral lesions.
