“…12 In this case, no lipid disorders were diagnosed. Other bone diseases that may also present xanthomatous features include Langerhans cell histiocytosis, benign fibrous histiocytoma and fibrous dysplasia, 3,13,14 which are usually solitary lesions. In this case, histopathological and immunohistochemical analyses, in addition to serum exams, were performed to confirm the diagnosis of primary bone xanthoma.…”

Bone xanthomas are rare and are usually are associated with endocrine or metabolic diseases, mainly lipid disorders. In the absence of systemic diseases, the lesion is called a primary xanthoma. Primary mandibular xanthomas are extremely rare. The aim of this report is to describe the clinical and radiographic findings of a primary mandibular xanthoma, discussing the epidemiological features, pathogenesis and differential diagnosis. A 25-year-old man was referred for evaluation of a left mandibular lesion detected in a routine radiographic exam. Radiographically, there was a diffuse, unilocular and radiolucent lesion, with irregular margins located adjacent to the surface from the distal root of the left mandibular third molar. The lesion was excised under local anaesthesia. Microscopically, there were several cells with a foamy and granular cytoplasm and central small, round nuclei, similar to xanthomatous macrophages. No lipid disorders were diagnosed. According to these features, the diagnosis of primary mandibular xanthoma was established. In conclusion, xanthomas of the jaws are rare and all seem to be primary and occur exclusively in the mandible. Dentomaxillofacial Radiology (2011) 40, 393-396. doi: 10.1259/dmfr/51850495Keywords: jaws; mandible; xanthoma Case reportA 25-year-old man was referred to a private oral surgery clinic for an evaluation of a left mandibular lesion detected in a routine radiographic exam performed during orthodontic treatment. Medical history was not contributory and the patient denied pain or previous local trauma, including surgical procedures. At the extraoral examination, the face was symmetric, with a normal contour of the inferior portion of the face. On intraoral examination, the patient showed well conserved dentition and oral mucosa with a normal colour and texture without lesions or swelling. It was noted that the patient was undergoing orthodontic treatment owing to the presence of orthodontic brackets fixed to the crown of the teeth. Radiographically, there was a diffuse, unilocular and radiolucent lesion with irregular margins, located adjacent to the surface of the distal root of the left mandibular third molar, measuring approximately 2.0 cm (Figures 1 and 2). In this region, the upper and lower limits of the mandibular canal were not observed. The left mandibular third molar was intact and no percussion pain, facial paraesthesia or paralysis or periodontal pockets in the distal surface were observed.As the lesion presented diffuse and irregular margins, and no inflammatory signs and symptoms were observed, a primary or metastatic malignant neoplasm was considered as the main hypothesis of diagnosis. To establish the diagnosis, the patient was submitted to an incisional biopsy of the lesion under local anaesthesia. During the surgical procedure, it was observed that there was no continuity between the lesion and the oral cavity. Additionally, after accessing the local area surrounding the lesion, a bone cavity filled with a yellowish, soft and amorphous tissue was n...

“…8,10 To our knowledge, there have been only 5 case reports of a BFH in cranial bone and no cases of BFH in the neurocranium. 3,11,14,21,24 The present case was also characterized by increased intracranial pressure accompanied by sinus occlusion caused by this skull tumor. We present the first reported case of BFH in the neurocranium, including its management in the perioperative period, and a review of the literature.…”

The authors present a very rare case of benign fibrous histiocytoma of the skull with increased intracranial pressure caused by sinus occlusion. A 33-year-old woman was referred for investigation of a right occipital protrusion with tenderness and double vision. She had only mild divergence insufficiency and bilateral papilledema neurologically. Imaging findings showed that the skull tumor was located at the right occipital bone with bone disruption and a compressed right sigmoid sinus. When planning the resection, caution was required to spare the collateral flow so as to manage the intracranial pressure. Immunohistochemical analysis showed that the tumor was positive for CD68, alpha1-antichymotrypsin, and alpha1-antitrypsin. From these findings, the tumor was diagnosed as a primary benign fibrous histiocytoma of the skull.

“…NOF is centered in the metaphysis of the long bones and radiologically show a lytic lesion with a sharply circumscribed sclerotic rim, whereas BFH occurs in non-long bones, or lack of metaphyseal involvement even if in a long bone. Furthermore, radiographic sclerotic rim is generally seen in NOF, but not in BFH [14].…”
