Choriocarcinoma is extremely aggressive form of gestational trophoblastic disease. It occurs due to neoplastic changes in the chorionic villi. The most common site of origin is uterus but rarely can occur in tube, cervix or ovary. Tubal choriocarcinoma may develop either by malignant transformation of a tubal pregnancy or can arise denovo without an ectopic pregnancy. The reported incidence of tubal choriocarcinoma is approximately 1.5/1,000,000 births. Here, we report a case in which salphingectomy was done thinking it was an acute ectopic pregnancy, but histopathological examination showed tubal choriocarcinoma. This tubal choriocarcinoma occurred denovo and was not secondary to an ectopic pregnancy. Patient did not need adjuvant chemotherapy as it was detected early and is being followed up by β-hcg monitoring.

Conventional spin-echo (SE) and contrast-enhanced dynamic MR imaging were performed on a 1.5 T superconductive unit for evaluation of myometrial lesions in postmolar gestational trophoblastic disease (GTD) in 10 women. MR imaging was done at the time of the initial examination (n=10), during (n=6), and after repeated courses of chemotherapy (n=10). The T2-weighted SE image revealed an enlarged uterus (n=7), disappearance of zonal anatomy (n=6), and heterogeneous signal intensities (n=8) with prominent flow voids (n=7). However, these abnormalities remained after repeated courses of chemotherapy, when the S-β-HCG level returned to the normal range. Myometrial lesions characteristically had marked enhancement with areas of unenhancement on dynamic MR images in patients with highly elevated S-β-HCG. Areas of contrast enhancement correlated with changes in S-β-HCG level. The enhancement was reduced with decrease in S-β-HCG level after repeated courses of chemotherapy. Six of 8 masses seen on T2-weighted images proved to be active trophoblastic lesions and 2 masses proved to be hematoma or necrosis. In 2 patients, abnormal myometrial lesions were detected only on contrast-enhanced dynamic MR imaging. These preliminary data indicate that contrast-enhanced dynamic MR imaging more clearly demonstrates myometrial involvement of postmolar GTD than conventional SE imaging.

This review provides an overview of spontaneous abortion, ectopic pregnancy, gestational trophoblastic disease or molar pregnancy, hyperemesis gravidarum, placental abruption, placental previa, hypertensive disorders of pregnancy, and amniotic fluid embolism. Assessment and stabilization, diagnosis, treatment and disposition, and outcomes are discussed. Tables include classifications of abortion or miscarriage, differential diagnosis of patients presenting with vaginal bleeding during pregnancy, risk factors for ectopic pregnancy, treatment modalities for hyperemesis gravidarum, classification of hypertensive disorders of pregnancy, and risk factors for preeclampsia and eclampsia. Figures show ectopic pregnancy on a sonogram, free fluid in hepatorenal fossa on a focused abdominal sonogram in trauma, double decidual sign in a normal intrauterine pregnancy, pseudogestational sac in an ectopic pregnancy, and “snowstorm” appearance of molar pregnancy on a sonogram.

Ectopic molar pregnancy is a rare occurrence. Clinical diagnosis of a molar pregnancy is difficult but histopathology is thegold standard for diagnosis. The management of ectopic molar pregnancies consists of surgically removing the conceptus, follow up &chemotherapy, if required. We are reporting a case report of a 35-year-old married, nulliparous woman, admitted in emergency with a 6-week history of amenorrhea, severe abdominal pain & an episode of fainting at home. Per abdominal examination revealed tendernessover the right iliac fossa, with guarding & rigidity. Diagnosis of ruptured ectopic pregnancy was made.Emergency laparotomy was done.Histopathological examination, showed tubal ectopic pregnancy with partial hydatidiform mole & a separate corpus luteal cyst.She wasfollowed up with serial beta hCG which became normal within 1 month. Although ectopic molar pregnancy is a rare entity but all ectopicpregnancies should be examined histologically to rule out presence of gestational trophoblastic disease to plan follow-up accordingly inorder to avoid persistent gestational trophoblastic disease which has a chance of malignant conversion.The prognosis of ectopic molarpregnancies is the same as for other forms of gestational trophoblastic disease.
