GRANULAR-CELL TUMOR OF THE BILE-DUCT IN ASSOCIATION WITH INTRAHEPATICBILE-DUCT ADENOMAS

Granular cell tumour of the extrahepatic biliary tract is a rare benig n lesion likely of neurogenic origin. Review of the previously reporte d cases indicates that almost all patients are female, and the majorit y is Black. Symptoms usually are those of biliary obstruction or chole cystitis. Surgical resection of the tumour is curative. Intrahepatic b ile duct adenoma is another rare benign biliary neoplasm that does not manifest clinically but can be confused with metastatic carcinoma, ch olangiocarcinoma or other focal liver lesions at laparotomy or autopsy . The authors report the case of an asymptomatic Caucasian woman with biochemical evidence of liver disease who had a granular cell tumour o f the bile duct as well as several intrahepatic bile duct adenomas.
