• hepatic lipoma

  2 August

  As with lipomas elsewhere in the body, hepatic lipomas are marginated masses that are composed of mature adipocytes without evidence of cellular atypia.
  Histopathologic evaluation may reveal adenomatous, angiomatous, or myomatous tissue components, which may then yield a classification of "adenolipoma", "angiomyolipoma", or "myelolipoma".
