Primary cancer of the appendix, especially signet-ring cell carcinoma, is an uncommon disease, and it is rarely suspected before surgery. Diffuse intestinal ganglioneuromatosis that is not associated with neurofibromatosis-1 or multiple endocrine neoplasia 2b is also rare. The most frequent symptoms caused by it are changes in bowel habits, abdominal pain, and occlusive episodes.
