Background
Hibernoma is a rare benign tumor of adults that is composed of multivacuolated adipocytes resembling brown fat cells. Hibernoma typically occurs in soft tissue, and intraosseous examples are very rare. Intraosseous hibernomas can radiologically mimic metastatic carcinoma and other tumorous conditions. Methods: To collect the intraosseous hibernomas, we searched the pathologic database and reviewed the hematoxylin and eosin (H&E)–stained slides of bone biopsy samples performed to differentiate radiologically abnormal bone lesions from 2006 to 2016. A total of six intraosseous hibernoma cases were collected, and clinical and radiological information was verified from electronic medical records. H&E slide review and immunohistochemical staining for CD68, pan-cytokeratin, and S-100 protein were performed. Results: Magnetic resonance imaging of intraosseous hibernomas showed low signal intensity with slightly hyperintense foci on T1 and intermediate to high signal intensity on T2 weighted images. Intraosseous hibernomas appeared as heterogeneous sclerotic lesions with trabecular thickening on computed tomography scans and revealed mild hypermetabolism on positron emission tomography scans. Histopathologically, the bone marrow space was replaced by sheets of multivacuolated, foamy adipocytes resembling brown fat cells, without destruction of bone trabeculae. In immunohistochemical analysis, the tumor cells were negative for CD68 and pan-cytokeratin and positive for S-100 protein. Conclusions: Intraosseous hibernoma is very rare. This tumor can be overlooked due to its rarity and resemblance to bone marrow fat. Pathologists need to be aware of this entity to avoid misdiagnosis of this rare lesion.

Abstract PDF

Neurilemmoma (Schwannoma) is a benign nerve sheath tumor that's composed entirely of well-differentiated Schwann cells. Intraosseous neurilemmomas are rare and they represent less than 1% of all benign primary bone tumors. We report here on an additional case of intraosseous neurilemmoma that was located in the mandible of a 77-year-old woman. CT revealed an expansile, well-defined lesion on the right side of the mandibular body with thinning of the cortex. The lesion was surgically removed and it was found to be a 2x1.7 cm-sized, bright yellowish, hard mass with hemorrhage and cyst formation. Histologically, the mass was a moderately cellular neoplasm and it showed distinct nuclear palisading, numerous Verocay bodies and tumor cells that were positively immunohistostained for S-100 protein. Two months after the operation, the patient has remained in a good condition with no signs or symptoms of tumor recurrence.
