Which of the following statements is true about benign lesions of the liver?
assistant
The correct answer is  Adenomas typically enlarge and cause symptoms, may rupture, and have a definite malignant potential. Therefore they should generally be resected when found. FNH is not a true neoplasm and generally has an uneventful course. Both are related to BCPs, although the relationship of adenoma is more firmly established. While small bile duct hamaomas are much more common, hemangiomas are the most common lesion to come to the attention of surgeons. They should not generally be biopsied because of possible hemorrhage. By definition, nodular regenerative hyperplasia occurs in the absence of cirrhosis.
