Facial leontiasis ossea: a rare presentation of hyperparathyroidism secondary to chronic renal insufficiency.
The term renal osteodystrophy is often used in a generic sense to include skeletal disorders of patients with chronic renal failure due to secondary hyperparathyroidism. The prevalence of this condition among patients on hemodialysis is considerably high. However, extreme forms such as facial leontiasis ossea are very rare, only 2 well-characterized cases having been reported thus far in the literature. In the present article we report the case of a female patient who developed hyperparathyroidism secondary to end-stage renal disease which was manifested as facial leontiasis ossea and culminated in dysphagia and respiratory difficulties caused by excess bone tissue growth.
