Gynecological inflammation to some extent and pelvic malignant tumors have striking similarities: 1, both have significant weight loss, emaciation. 2, both have a history of chronic lower abdominal pain. 3, neither have a lot of leukorrhea. 4, neither have a high blood CA125. 5, all have outward invasiveness. That is, when we think of inflammation, it is a malignant tumor (pelvic CT is normal, CA125 is not high), when we suspect malignancy, he is indeed inflammation (and this patient’s preoperative pelvic CT lymph nodes are enlarged, infiltration to the uterus and bladder). It is the complexity and diversity of the disease.
