Exaggerated placental site, a trophoblastic benign lesion, is characterized by an extensive infiltration of the endometrium, myometrium and arterial walls by intermediate trophoblast cells. Trophoblastic benign lesions are often an incidental finding in the anatomopathological study, but may be associated with severe bleeding especially in relation to trauma. Case report: Multigravida 39 years old with excessive uterine bleeding after medical treatment of abortion. Once expelled gestational vesicle is seen sonographically a uterine cavity occupied by a heterogeneous endometrium with maximum anteroposterior diameter of 21 mm, plenty of color map, reaching myometrium. B-HCG serum is 164 mlU/ml. During hysteroscopy a massive bleeding happens and its necesary to use an intrauterine catheter to stop it. Computed tomography angiography shows suggestive findings of uterine vascular malformation. A hysterectomy as a diagnostic and definitive treatment is made and pathology reports an exaggerated placental site.
