Tubal pregnancy complicated with rudimentary horn: two case reports and literature review

The incidence of müllerian duct anomalies has been estimated in 0.16–10% of all women and unicornuate uterus accounts for 4–5% of these cases (1-3), although the true incidence is unknown. Although tubal pregnancy is the most common ectopic pregnancy, tubal pregnancy in a unicornuate uterus with rudimentary horn has rarely been documented. Here we present the clinical manifestations and management of two cases of tubal pregnancy in a unicornuate uterus with rudimentary horn and reviewed the literature on this topic. We present the following cases in accordance with the CARE reporting checklist (available at https://dx.doi.org/10.21037/gpm-21-43).
