title: Intraosseous Hibernoma in the Sacrum of an Adult.
abstract: Hibernoma is an uncommon lipomatous tumor composed of brown adipose cells that until recently has only ever been described in soft tissue locations. This report describes the histological features of a discrete lesion in the sacrum of an 84-year-old lady. Biopsy of this lesion demonstrated that it consisted predominantly of multivacuolated lipocytes with a morphological and immunohistochemical profile consistent with brown fat cells. The lesion was diagnosed as an intraosseous hibernoma. This is the 16th report in the English literature of a hibernoma occurring outside of a soft tissue location.
