Osteomas of the gallbladder.

A 39-year-old woman had multiple osteomas of the gallbladder. She presented with right upper quadrant abdominal pain associated with leukocytosis. An ultrasound showed three small intraluminal gallbladder lesions with no apparent mobility. The lesions proved to be three small polypoid osteomas in the resected gallbladder. A review of the literature showed no previous report of this type of gallbladder neoplasm.
