<unk>  is formed from mature adipocyte cells and is histologically indistinguishable from fat tissue. Recent studies have observed cytogenetic abnormalities in 50-60% of<unk> s, suggesting its role in the<unk>  pathogenesis. Rearrangements of chromosome 12 are the most commonly cytogenetic abnormality. In a cross-sectional appearance, the<unk>  is pale yellow to orange and has a uniform greasy surface with a lobular pattern. The subcutaneous<unk>  is usually encapsulated and has a distinct lobulated pattern.
