Advanced abdominal pregnancy is extremely rare. Symptoms are often nonspecific, and the diagnosis is frequently missed. Maternal mortality and morbidity are also very high especially if the condition is not diagnosed and managed properly. In abdominal pregnancy there is a high incidence of fetal malformations. We are presenting a case of a 38 year old primigravida with an undiagnosed advanced abdominal pregnancy carried beyond 36 weeks of gestation. We delivered a 2090 g baby from the abdomen. A relaparotomy was necessary on the third postoperative day because of abdominal bleeding. At the time of discharge both mother and baby were doing well. The publication also provides a literature overview, including definition, epidemiology, diagnosis and therapy. Orv. Hetil., 2017, 158(13), 508-511.
