Abstract:
Xanthomas of soft tissue are common, well described lesions. Much less common are xanthomas of bone. Rarer still are xanthomas of the bones of the skull or facial skeleton. The case of a woman with an incidentally found isolated xanthoma of the frontal bone in the setting of normal blood lipid levels is reported. Surgical treatment of such lesions is both diagnostic, in excluding other lesions such as eosinophilic granuloma, and therapeutic.

The frontal bone is thickened just above each supraorbital margin,...

Below this area and projecting anteriorly is the zygomatic process of the temporal bone, which forms the posterior portion of the zygomatic arch. Posteriorly is the mastoid portion of the temporal bone. Projecting...
