Abstract: Ectopic pregnancy is a common gynecologic acute abdominal disease， and along with the increase of gynecological inflammation，sexual transmitted disease，uterine cavity operation and caesarean section，the incidence of special ectopic pregnancy(SEP) is increasing over past several years. SEP includes caesarean scar pregnancy，ovarian pregnancy，rudimentary uterine horn pregnancy，cervical pregnancy and abdominal pregnancy. Some ectopic pregnancies are especially difficult for early diagnosis and have the risk of mis diagnosis，thus becoming life-threatening，because they have generally few apparent clinical features and signs which，if any，are not typical. With the application of ultrasonic skills within the diagnosis of pregnancy and the widely acceptance of the awareness of bearing and rearing better children，the threats of ectopic pregnancy is reducing year by year. The three major clinical features are menopause，abdominal pain，and vaginal bleeding，and different sort of SEP has its typical features each. It is an urgent issue for gynecological surgeons and emergency department of general hospital that the typical features of SEP，early diagnosis and timely treatment be emphasized.
