Unusual presentations of ectopic pregnancy. A report of two cases.

Extrauterine, or ectopic, pregnancy (EP) is located in the fallopian tube 95-97% of the time. EP occasionally continues to term, either in the abdomen or, more commonly, in the tube or ovary. Fistulae between the conceptus and the abdominal viscera or abdominal wall are most uncommon. Two rare clinical presentations of EP occurred at Good Shepherd Hospital. One was an advanced tubal pregnancy that formed a fistula with the abdominal wall and delivered spontaneously through the fistula, requiring surgical intervention. The second was an early tubal pregnancy that formed a fistula with the ileum, leading to severe rectal hemorrhage.
