● Frequent complication of allogeneic hematopoietic cell transplantation
● Usually affects skin, GI tract, liver
● Liver damage due to donor lymphocytes attacking liver epithelial cells, appears 10-50 days after bone marrow transplant
● Responds to immunosuppressive therapy (Blood 2002;100:3903, Transplantation 2004;77:1252)
● Diagnosis: elevated serum alkaline phosphatase > 2x normal, liver biopsy with typical features and no other cause for cholestatic liver disease after ultrasound, biopsy and follow-up
● Damage to > 50% of bile ducts with vacuolated cytoplasm, nuclear pleomorphism and necrosis of individual cells (apoptosis)
● Lymphocytic infiltrate of portal tracts and veins (endothelialitis) with lifting of endothelium from its basement membrane
● May also have ballooning degeneration or acidophil bodies
● Note: inflammatory infiltrate is limited because of bone marrow suppression early after transplant
● Viral hepatitis and drug related hepatitis (little bile duct damage)
● Am J Surg Pathol 2000;24:1004
