• ovarian dysgerminoma
  22 December 2005

  Definition: a primitive germ cell tumor, similar to testicular seminoma. A dysgerminoma is a type of germ cell tumor; it usually is malignant and usually occurs in the ovary.
  Dysgerminoma (seminoma) has fibrous septae infiltrated by lymphocytes. It also tends to arise out of intratubular germ cell neoplasia. If syncytiotrophoblast is present, it may have elevated hCG.

• sacrococcygeal teratoma
  18 July 2004

  Sacrococcygeal teratoma (SCT) is the most common tumor of the newborn with an incidence of 1 in 35,000 to 40,000 live births.
  In the newborn, the sacrococcygeal site is located at the base of the tailbone (coccyx), is the most common location of teratomas in newborns.

  JRC:4371 : Juxtacortical chondroma.
  Clinical synopsis
  Soft tissue chondroma is a rare benign cartilage lesion that has also been called extraskeletal chondroma or chondroma of soft parts. It occurs most commonly in the soft tissues of the hands and feet. The majority are located in the hands and wrists, especially in the fingers. The tumor is typically associated with a tendon, tendon sheath or joint capsule.
  They can be seen in patients of any age, but most are (...)

• seminoma

  seminoma of the testis, testicular seminoma; pure seminoma ; classical seminoma WKP
  Definition: Seminoma is a germ cell tumor of the testicle or, more rarely, the mediastinum or other extra-gonadal locations. It is a malignant neoplasm and is one of the most treatable and curable cancers, with a survival rate above 95% if discovered in early stages.
  Classic seminoma, far and away the most common of the two categories.
  Testicular seminoma originates in the germinal epithelium of the (...)

• 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 (...)
