• ovarian yolk sac tumor
  10 March 2004

  Definition: Malignant germ cell tumor of the ovary developed as a result of differentiation of primitive malignant germ cell elements in the direction of yolk sac or vitelline structures (endodermal sinus tumor).
  Yolk sac tumor has the pathognomonic Schiller-Duval body, consisting of a central blood vessel surrounded by germ cells. Serum AFP and alpha-1-antitrypsin are elevated. It stains by IHC for AFP, CD10 and CK. It is frequently in association with a benign teratoma.

• extraneural hemangioblastoma
  1 October 2007

  Hemangioblastoma is a morphologically distinctive tumor that can occur sporadically or in association with von Hippel-Lindau disease, and which involves the central nervous system in the majority of the cases (intraneural hemangioblastomas.
  Rare occurrences of hemangioblastoma in peripheral nerves and extraneural tissues have been reported.
  The histogenesis of this tumor remains uncertain. Various cell lineages such as vascular, glial, neural, fibrohistiocytic, and smooth (...)

  29 October 2004

  mature cystic teratoma of the ovary; OMCT, MCTO
  Definition: Mature cystic teratomas (MCTs) of the ovary are typically composed of a cyst lined with neoplastic tumor cells recapitulating ectodermal differentiation including derivatives such as epidermis, dermis, and appendages (sebaceous glands), although mesodermal and endodermal derivatives can also be seen.
