  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 (...)

• rectal neuroendocrine tumor
  27 March 2015

  According to the 2010 World Health Organization classification, all gastrointestinal neuroendocrine tumors (NETs) are classified as malignant except for L-cell-type (glucagon-like peptide [GLP] and peptide YY [PYY]-producing) NETs.
  Non-L-cell immunophenotype and large tumor size are associated with increased tumor grading and staging, concurrently indicating that they are independently poor prognostic indicators in rectal NET patients. Therefore, combining L-cell phenotype and tumor size (...)

  intravascular bronchioalveolar tumor, IVBAT, PEH, TEH
  Pulmonary epithelioid hemangioendothelioma (PEH), previously known as "intravascular bronchoalveolar tumor," is a rare vascular malignancy with an unpredictable prognosis.
  Treatment can vary from observation in asymptomatic patients to surgery in patients with resectable disease or chemotherapy in patients with disseminated disease.
  Pulmonary epithelioid hemangioendothelioma (PEH) is a rare vascular tumor. It can present either as one (...)

• vulvovaginal aggressive angiomyxoma

  Digital case
  JRC:15102 : Vulvar angiomyxoma, angiomyofibroblastoma variant.
  Definition: Aggressive angiomyxoma is a rare mesenchymal neoplasm, which almost always occurs in the vulvovaginal region and which exhibits a marked tendency for local recurrence after excision.
  A wide range of other mesenchymal lesions occur in this region, which potentially mimic aggressive angiomyxoma to a variable extent.
  The HMGA2 gene has been overexpressed in a significant percentage of aggressive (...)

• ovarian Sertoli-Leydig cell tumor
  3 July 2007

  ovarian androblastoma; ovarian Sertoli-Leydig cell tumour
  Definition: Sertoli-Leydig cell tumour is a group of tumors composed of variable proportions of Sertoli cells, Leydig cells, and in the case of intermediate and poorly differentiated neoplasms, primitive gonadal stroma and sometimes heterologous elements. (WHO, 2003) Sertoli-Leydig cell tumors (SLCT) comprise less than 1% of ovarian tumors.
