Ectopic pregnancy occurs when a fertilized egg implants outside of the uterus, usually in the fallopian tubes. Risk factors include age, prior pelvic infections or surgeries. Patients often present with vaginal bleeding and abdominal pain. Diagnosis is made through ultrasound and beta-hCG levels. Treatment involves surgery or medication to remove the pregnancy. Gestational trophoblastic disease is a spectrum of conditions stemming from abnormal placental tissue, including molar pregnancies and choriocarcinoma. It is diagnosed through beta-hCG levels and ultrasound or biopsy. Treatment may involve surgery and chemotherapy depending on severity. Long term monitoring of beta-hCG is important after treatment.
