Xanthomas manifest as yellowish papules, plaques, or nodules and are characterized by lipid-laden macrophages (foam cells). Xanthoma of bone is extremely rare and, when present, is often secondary to dyslipidemias or endocrine disorders. The former would be considered a secondary intraosseous xanthoma of bone. A xanthoma that is identified within bone in the absence of dyslipidemia or endocrine disease is considered a primary intraosseous xanthoma. When a xanthoma presents in the maxilla or mandible, it is considered an intraosseous xanthoma of the jaw. The first intraosseous xanthoma of the jaw was reported in 1964 and was referred to as a xanthogranuloma of the mandible. Since that initial report, less than 60 total cases have been reported in the English literature. The cases reported are typically small in size and amenable to enucleation and curettage.
