Intermittent jaundice and right upper quadrant pain arc the most common symptoms. The treatment of choice is local excision.
These tumors include adenomas, cystadenomas, fibroadenomas, adenomyomas, and hamartomas. Adenomas, which are frequently associated with gallstones and cholecystitis, may have malignant potential. Symptoms and signs may be nonexistent, vague, or typical of acute or chronic cholecystitis. Diagnosis is made by demonstrating a filling defect in the gallbladder.

The relationship of colonic polyps [...]
Usually these benign neoplasms occur in the fifth, sixth, and seventh decades of life. About 80% of them occur in the jejunum and ileum. Adenomatous polyps are the most common benign neoplasms, followed by leiomyoma, lipoma, and hemangioma. In the small intestine, as in the rest of the GI tract, adenomatous polyps are premalignant. Villous [...]
