pipestem fibrosis

pipe·stem fi·bro·sis

a characteristic pipe-shaped fibrosis formed around hepatic portal veins in some cases of long-continued heavy infection with Schistosoma mansoni; thought to be induced by the presence of large numbers of schistosome eggs in the hepatic tissues.
A descriptive term for the histologic appearance—portal vein fibrosis with hyaline thickening and tortuosity of vessels—of portal spaces in liver involvement by Schistosoma mansoni and S mekongi; schistosomal hepatopathy mimics cirrhosis with hepatosplenomegaly, portal hypertension, secondary hypertension, and variceal bleeding; native architecture is preserved
