An advanced abdominal twin gestation after primary infertility and after tubal pregnancy.

A developing extra-uterine intra-abdominal gestation is very rare. In the literature the incidence varies from 1 : 6389 to 1 : 10,200. Our case concerns an abdominal ectopic twin gestation, exclusively in relation with the peritoneal surface, which developed normally until 13 weeks and then died.
