title: Angiolipoma in head and neck: report of two cases and review of the literature.
abstract: Angiolipomas are either encapsulated or non-encapsulated fatty tumours. They are distinguished from other lipomas by the excessive degree of vascular proliferation and because they are mixed with mature adipocytes. They commonly occur in the trunk and extremities and are rare in the maxillofacial area. Only 36 cases in the head and neck have been reported in the literature. The authors report the first non-infiltrating intramasseterine angiolipoma, and a case of non-infiltrating angiolipoma of the cheek. These tumours appear as homogenous low-density areas on CT with no contrast enhancement. MRI gives better tumour delineation and clear definition of the location and longitudinal extent of the mass. Histopathology demonstrates mature adipose tissue and the proliferation of numerous small branching blood vessels. Management of angiolipomas requires complete surgical excision.
