title: Immature omental teratoma.
abstract: Immature omental teratomas are extremely rare neoplasms. To our knowledge, only two cases have been reported in the literature. In some anatomic locations, the malignant potential of immature teratomas correlates with the presence and quantity of neuroectoderm within the tumor mass. We describe the first immature omental teratoma with prominent neuroectodermal differentiation.
