LEONTIASIS OSSEA Dr Jeremy Jones and Dr Frank Gaillard et al. . Leontiasis ossea is a largely historical term used to describe a number of conditions that result in the affected patients face resembling that of a lion. Although it is most frequently associated with craniofacial fibrous dysplasia, it has a broader meaning encompassing other lesions that have similar appearance 1,4. The distinction is made between true leontiasis ossea (craniofacial fibrous dysplasia) and other conditions having similar external appearance (mimics), however it would be safe to say that as a term it is no longer of clinical use and should be avoided. In addition to craniofacial fibrous dysplasia the following conditions may mimic leontiasis ossea: •Paget disease •gigantism •craniosysonstosis •tumours of the paranasal sinuses •syphilitic osteoperiostitis •ureamia with secondary hyperparathyroidism 2 Etymology The famed Virchow first coined the term leontiasis ossea in 1864 3. Rudolf Ludwig Karl Virchow (1821-1902) was a German pathologist and statesman 5. References 1. Evans J. Leontiasis ossea; a critical review, with reports of four original cases.
