A benign tumor containing vascular, adipose, and muscle elements; it occurs most often as a renal tumor with smooth muscle elements (more correctly called angiolipoleiomyoma) usually in association with tuberous sclerosis, and is considered to be a hamartoma (a benign tumor-like nodule composed of an overgrowth of mature cells and tissues that normally occur in the affected part but with disorganization and often with one element predominating).
