    "abstract": "Ectopic pregnancy occurs when a developing blastocyst implants at any site other than the uterine cavity. Ectopic pregnancy is most commonly found in the fallopian tube but may also occur in the cornua of the uterus (also found as interstitial in the literature), cervix, ovary, or abdominal cavity or in a cesarean scar. An estimated 2% of pregnancies are ectopic, of which an interstitial pregnancy represents an extremely rare variant of ectopic pregnancy (EP), accounting for 2% to 4 % of all cases. The aim of this report is to describe the case of a patient with suspected ectopic pregnancy of uncertain location in which an exploratory laparoscopy was performed due to the onset of symptoms, discovering a cornual ectopic pregnancy in site of a past salpingectomy because of a tubal ectopic pregnancy. A cornuotomy by laparoscopy was performed to resect the cornual ectopic pregnancy. The patient had an uneventful postoperative course, with negativization of human chorionic gonadotropin levels. This type of location is rare and is associated with high rates of maternal morbidity and mortality. It represents a diagnostic and therapeutic challenge for the gynecologist who faces it.\nSe define a un embarazo ect\u00f3pico cuando el blastocisto en desarrollo se implanta fuera de la cavidad uterina. La localizaci\u00f3n m\u00e1s frecuente es en la trompa, pero tambi\u00e9n puede ocurrir en el ovario, c\u00e9rvix, cicatriz de ces\u00e1rea, cuerno uterino (tambi\u00e9n mencionado como intersticial en la literatura) o abdominal. Se estima que la incidencia de embarazo ect\u00f3pico es aproximadamente el 2% de todos los embarazos, siendo la localizaci\u00f3n cornual solo el 2-4% de esos casos. El objetivo de este reporte es describir el caso de una paciente con sospecha de embarazo ect\u00f3pico de localizaci\u00f3n incierta a quien se le realiz\u00f3 una laparoscopia exploradora por inicio de s\u00edntomas, evidenciando un embarazo ect\u00f3pico cornual en el lecho de una salpingectom\u00eda, producto de un embarazo ect\u00f3pico tubario previo. Se realiz\u00f3 la cornuotom\u00eda con resecci\u00f3n del mismo por laparoscopia y su evoluci\u00f3n fue favorable con negativizaci\u00f3n de la subunidad beta. Este tipo de localizaci\u00f3n es rara y se asocia con grandes tasas de morbimortalidad materna. Representa un desaf\u00edo diagn\u00f3stico y terap\u00e9utico para el ginec\u00f3logo que lo enfrenta.",
