AbstractPlacental polyp is retained placental tissue within the endometrial cavity, which forms a nidus for inflammation and bleeding. There are very few reported cases of the clinical placental polyp. Here, we report a case of 34-year-old G4L3Ab1 woman with the chief complaint of intermittent vaginal bleeding since her last normal vaginal delivery 3 months ago. Serum human chorionic gonadotropin (hCG) titer was slightly elevated. A polypoid mass was detected within the endometrial cavity by imaging studies. History of the patient, mass lesion within the endometrial cavity and slightly elevated serum hCG titer raised the suspicion of trophoblastic neoplasms. Endometrial curettage yielded unsatisfactory specimen containing only fibrin deposition and was followed by total hysterectomy. The uterus showed slight global enlargement resulting from the presence of a polypoid mass within the endometrial cavity. The red-colored mass had a smooth outer surface and fragile consistency without any permeation into the myometrium. Pathology reported it as the placental polyp. Although very rare, placental polyp should be kept in mind as one of the reasons of abnormal uterine bleeding in parous women. Definite diagnosis is made by pathology examination.
