Embarazo ectópico ovárico. Caso clínico y revisión del tema

Summary A case of a 21-year-old single woman with an acute abdomen, vaginal bleeding and an anemic syndrome is presented. Physical examination and ultrasonography showed an enlarged uterus and a little mass in the right ovary, which was thought to be a fibroma versus pregnancy. Serum levels of chorionic gonadotropin were increased. Abundant black blood loose was found in the peritoneal cavity in the surgery performed. Through a wedge resection, a small hemorrhagic nodule was removed from the surface of the right ovary. Microscopic examination showed ovarian stroma, immature chorionic villi and intermediate extravillous trophoblast, which supported the diagnosis of ectopic ovarian pregnancy. This complication requires an opportune diagnosis, because it continues to be one of the leading risk factors in surgical gynecological emergencies and the first cause of maternal death during the first trimester of pregnancy. A brief review on the subject is presented.
