Peritoneal implants secondary to a tubal ectopic pregnancy or extratubal omental secondary trophoblastic implants (ESTI) are a rare entity often underestimated or unknown. It can be responsible of rising in the ß-hCG titer after salpingectomy for ectopic tubal pregnancy. Moreover, implants on the omentum are exceptional. This particular localization is exceptional and its physiopathology, diagnosis, surgical management and follow-up are discussed in this paper.
