The ectopic pregnancy refers to a gestation in which the fertilized ovum implants on any tissue other than the mucous membrane lining the uterine cavity. The most common site of ectopic pregnancy is within the fallopian tube including interstitial portion. Moles usually occupy the uterine cavity; they rarely may be located in the oviduct and even in the ovary. Only a few cases of primary hydatidiform mole of the tube have been reported. We reported an extremely rare case of ectopic hydatidiform mole in the interstitial portion of the tube.
