Estrogens are commonly used in gynecologic area, such as oral contraception, hormone replacement therapy, and in vitro fertilization-embryo transfer. Although estrogen is a common cause of acute drug-induced pancreatitis, there has been paucity of report in Korea. Clinical course of estrogen-induced acute pancreatitis is usually mild to moderate, but fetal case can occur. In addition, there can be a latency from the first administration to the symptom. Therefore, physicians should consider the possibility of the disease when a woman taking estrogen or previous history of taking estrogen presents with acute abdominal pain. Here, we report a case of estrogen-induced acute pancreatitis that occurred during the preparation for embryo transfer.
