LARREA, Agustina L.  y  BOZZA, Lorena A.. Interstitial ectopic pregnancy: report of an unusual location. Medicina (B. Aires) [online]. 2023, vol.83, n.6, pp.986-989. ISSN 0025-7680.

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 pregnan cies are ectopic, of which an interstitial pregnancy repre sents 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 unevent ful 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.
