RESUMENObjetivos: reportar el caso de un embarazo cervical (EC) que recibió manejo conservador exitoso y realizar una revisión de la literatura sobre el tratamiento médico y quirúrgico conservador. Materiales y métodos: se presenta el caso de una paciente con embarazo cervical, quien recibió manejo farmacológico con metotrexate (MTX) y posterior legrado con evolución clínica satisfactoria. Se realizó una búsqueda de artículos en Medline vía PubMed, LILACS, SciElo y Google académico con los términos: "cervical ectopic pregnancy", "conservative treatment", "curettage", "methotrexate", ABSTRACT Objectives: To report a case of cervical pregnancy (CP) treated successfully with a conservative approach, and to conduct a review of the literature regarding conservative medical and surgical treatment. Materials and Methods: Patient with cervical pregnancy treated pharmacologically with methotrexate (MTX) followed by dilation and curettage, with a satisfactory clinical course. A search of articles was conducted in Medline via PubMed, LILACS, SciElo and Google Scholar using the terms "cervical ectopic pregnancy," "conservative treatment," "curettage,» "methotrexate," "uterine artery embolization," "hysteroscopy." Reports and case series were selected of patients with cervical pregnancy diagnosed on ultrasound at any gestational age, subjected to conservative medical or surgical treatment. Results: A total of 22 studies were included; 95 patients with CP treated with MTX were identified, 93 of them successfully treated. The most frequent complication was bleeding in 12%; 26% required complementary surgical treatment. Increasingly, uterine artery embolization (UAE) is carried out preventatively (7 cases) before curettage or treatment with MTX. The hysteroscopy is another recent alternative (20 cases). Abdominal hysterectomy was required in two cases, one of which was a cervico-isthmic pregnancy. Conclusions:Treatment with MTX continues to be the most frequent strategy. Dilation and curettage with endocervical plugging may be an option to consider in the emergency management of EP in primary care institutions. In institutions equipped with high complexity technology, uterine artery embolization before the surgical procedure and histeroscopy are options to be considered. Considering that early diagnosis of EP is now possible, multi-center studies comparing different management options are needed for better assessment of their safety and effectiveness.

Lithopedion (lithos = rock and paidion = child) is a rare condition that only occurs in 1.5 to 1.8% of extrauterine pregnancies and in 0.00045% of all pregnancies. It consists of an ectopic pregnancy in which the fetus dies but cannot be reabsorbed by the mother's body, which then coats it in a calcium-rich substance. We present the case of a 77-year-old woman with an incidental diagnosis of a lithopedion, which had been retained in her left pelvis for presumably 40 years.
