Only a few cases have been found in this location to date. Although the annual incidence of lower gastrointestinal bleeding has been increasing, bleeding related to the appendix is quite rare. We herein present a very rare case of gastrointestinal stromal tumor incidentally found by appendiceal hemorrhage.展开更多
