Exaggerated Placental Site as a Cause of Hysterectomy for Massive Bleeding After First Trimester Voluntary Abortion

Objectives Placental implantation anomalies in first-trimester abortions may determine severe bleeding leading to hysterectomy. There are very few cases of urgent hysterectomy post-abortion reported in the literature, related to placenta accreta spectrum, but in any of them is considered association with benign trophoblastic lesions. Methods We report the case of a woman, who underwent surgical voluntary abortion by vacuum aspiration during first trimester, without any apparent surgical complications. Immediately, after this procedure, the patient had massive vaginal bleeding; an emergency hysterectomy was performed. Histological examination showed an exaggerated placental site (EPS). Results Morphological findings describe a trophoblastic tumor-like lesion, which differs from placenta accreta and often considered an asymptomatic occasional feature. Proliferative index, evaluated by double immunostain for CK8-18 and Ki-67, was unremarkable (<1%). Conclusions Only a single report in the literature describes a case of symptomatic EPS 65 after first-trimester abortion. Major attention should be paid to trophoblastic pathology in order to understand a possible relationship with uterine bleeding and to find a clinical, ultrasound or chemical indicator.
