title: Huge immature teratoma of the liver in an adult: a case report and review of the literature.
abstract: Teratoma tumors are tumors of childhood and, to the best of our knowledge, only 9 cases of hepatic teratoma and 1 case of immature teratoma of the liver had been reported in adults in the English literature. We present the second case of immature liver teratoma in a 22-year-old woman who presented with a 4-month history of abdominal pain and fullness sensation. A computed tomography (CT) scan of the abdomen and pelvis showed a huge well-defined heterogeneous mass in the right lobe of the liver containing fat, calcification, and cystic and solid parts, all suggestive of a teratoma. A right hepatectomy and an omentectomy were performed. The pathology report showed a 27 cm mass composed of ectodermal, mesodermal and endodermal components with minimal atypia and foci of immature components suggestive of immature teratoma, which is the largest liver teratoma to be reported. The patient was discharged in good health. During 8 months of follow-up, a CT scan and α-fetoprotein levels were both normal, and the patient is still alive.
