A Case of Mature cystic teratoma in Omentum / 대한산부인과학회지

The mature cystic teratoma of the omentum is a very rare tumor. It is generally believed that autoamputation and reimplantation of an ovarian tumor is the most common etiology of omental teratoma. Abdominal pain is the main presenting symptom of these tumors. A 41-year-old woman was admitted for pelvic mass. At laparotomy, a 8.5 x 7.0 x 7.5 cm mass was found in the pelvic cavity, attached to the omentum with adhesion to bladder. The histopathologic diagnosis was mature cystic teratoma in conjunction with the cyst wall is diffusely necrotic and calcified with hairs. The absence of the left ovary suggested that the tumor underwent autoamputation and reimplantation on the omentum. We report the case with a brief review of literature.

A case of ruptured omental pregnancy / 대한산부인과학회지

Abdominal pregnancy is a rare form of ectopic pregnancy, which has been classified as early and advanced abdominal pregnancies. In case of early abdominal pregnancy, we may miss the diagnosis because the symptoms and clinical characteristics are non-specific. However, recently, the early diagnosis is made because of the development of quantitative beta-hCG measurement, transvaginal ultrasonography and the development of laparoscopy. Omental pregnancy is a very rare form of abdominal pregnancy, which is hard to detect early. When ruptured, it accompanies with massive hemorrhage. So, early diagnosis and treatment is essential to prevent high morbidity, mortality and serious complications. Definite diagnosis is made by cytopathologic examination of tissue specimen after surgery. We have experienced a case of ruptured early omental pregnancy and reviewed it briefly.
