Overview

They arise from the endothelial cells that line the blood vessels and consists of multiple, large vascular channels lined by a single layer of endothelial cells and supported by collagenous walls.

Pathophysiology

Pathogenesis

  • They arise from the endothelial cells that line the blood vessels and consists of multiple, large vascular channels lined by a single layer of endothelial cells and supported by collagenous walls.
  • They may be associated with focal nodular hyperplasia.

Associated Conditions

May be associated with:

Gross Pathology

On gross pathology, variable in size, well circumscribed, classically subcapsular are characteristic findings of hepatic hemangioma.[1]

Microscopic Pathology

On microscopic histopathological analysis channels lined by benign endothelium containing RBCs, surrounding (non-endothelial) cells without significant atypia are characteristic findings of hepatic hemangioma.[1]
