[Bone lithiasis: experimental and clinical histopathology]

There is scant literature on bone lithiasis, a disease entity whose diagnosis depends fundamentally upon the anatomopathological findings. The data gleaned from animal experiments have been shown to overlap with those observed in the clinical setting. Conservative treatment should include resection of the urothelial bony metaplasia to avoid recurrence. The importance of making a correct diagnosis cannot be overemphasized since this condition may be associated with a tumoral lesion and a close follow-up is therefore warranted.
