Appendicitis caused by carcinoid tumor.
A previously healthy man had a carcinoid tumor that caused obstruction and dilatation of the appendiceal lumen, with subsequent inflammation of the appendix. He had acute pain in the lower right abdomen, loss of appetite, constipation, pyrexia, and an increased erythrocyte sedimentation rate without leukocytosis. Although his clinical signs and symptoms subsided, the persistent pathologic finding of a large dilated appendix at examination with ultrasound warranted surgery, which, with microscopy, established the correct diagnosis.
