Purpose: We present a case of ectopic pregnancy occurring in the stump of a remnant fallopian tube following ipsilateral adnexectomy for a mature cystic teratoma.
Methods: She had a laparoscopic salpingectomy.
Results: We hypothesize the intrauterine transmigration of the fecundated ovum.
Conclusions: The authors emphasize the rarity of the observed case.
