  • Very rare as primary hepatic tumor (< 100 cases reported); usually represents metastasis from GI tumor (small intestinal primaries may be very small)
  • Slightly more frequent in females
  • Rarely associated with Zollinger-Ellison syndrome, VIP production
  • Indolent low grade clinical course with prolonged survival but recurs or metastasizes more frequently than appendiceal carcinoids (Arch Pathol Lab Med 2003;127:1200)
