“…The initial differential diagnoses that should be excluded also include gastrointestinal diseases that include appendicitis, bowel obstruction, diverticulitis, gastritis, irritable bowel syndrome, and mesenteric venous thrombosis, and urinary tract diseases, including cystitis, and pyelonephritis. The diagnosis of ectopic pregnancy is more likely to be made in cases with an early presentation in the immediate period after hysterectomy, but this was a case with a late presentation, which is much rarer [1,3]. However, as this case has shown, even in late cases of ectopic pregnancy, measurement of serum levels of human chorionic gonadotropin (hCG) are important to make the diagnosis, although some malignant tumors can be associated with increased serum hCG, including hepatic, gastric, pancreatic, ovarian, and breast cancer as well as neuroendocrine tumors.…”
