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:
- Kasabach-Merritt syndrome
- Hemolytic anemia
- Consumptive coagulopathy
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.[2]
