BACKGROUND:

Zygote implantation in the cervix occurs in 0.1% of ectopic pregnancies. Its incidence has increased with assisted reproduction and elective abortion. Two cases and their medical management are presented.

FIRST CASE:

A 34-year-old primiparous patient who was diagnosed with incomplete abortion after six weeks of pregnancy. When a uterine curettage was performed, the uterine cavity was found empty and the presence of the gestational sac was demonstrated in the cervix. She was treated with methotrexate plus folic acid with successful results.

SECOND CASE:

30-year-old patient, two pregnancies and a C-section; He went to the office due to abdominal pain and intermittent transvaginal bleeding, with four months of evolution before hospitalization. The condition began after interrupting, on a scheduled basis, pregnancy in the first trimester, with medication and uterine curettage. In the review, the uterine fundus was 20 cm, with fetal heartbeat. The ultrasound showed a pregnancy of 19.5 weeks with placenta previa and later in the service of maternal-fetal medicine, the diagnosis of placenta accreta was established. In this case, the diagnosis of cervical pregnancy was made by magnetic resonance until week 37 and was resolved by cesarean section, achieving the birth of a live product.

CONCLUSIONS:

Ectopic cervical pregnancy is exceptional and difficult to diagnose; Its incidence is increasing. In pregnancies of the first trimester it is possible to indicate conservative medical treatments and some cases may come to an end.
