title: Infiltrating angiolipoma with phlebolith formation.
abstract: Angiolipomas are uncommon benign soft tissue tumors with both fatty and vascular components; they may be encapsulated or locally invasive. Three cases are reported in which phleboliths were present within infiltrating angiolipomas. The demonstration of phleboliths in a lipoma suggests the diagnosis of infiltrating angiolipoma rather than the usual encapsulated lipoma.
