In addition to the classic periampullary location, GPs have been reported in the pylorus,[2] jejunum, and appendix.[3] One case was associated with a duodenal diverticulum. Some GPs have been associated with neurofibromatosis.[5] Most cases range from 1 to 3 cm, although a 10-cm example has been reported.[6] Although the majority of GPs behave in a benign fashion, rare examples of malignant GPs have been documented.[4] The metastases usually contain the endocrine component of the tumor.
