  Case 66 (HPC:66) : Clear cell sarcoma of the kidney (CCSK)
  Definition: Clear cell sarcoma of the kidney (CCSK) is a malignant renal tumor of childhood with a propensity to metastasize to bone and other organs. CCSK is linked to internal tandem duplications (ITDs) of the BCOR gene.
  This tumor may also recur many years after its initial diagnosis. The average age (...)

  Fetal Lipoma, Infantile Lipoma, Embryonic Lipoma
  Definition: Lipoblastoma is a rare benign tumor that arises from embryonic adipose tissue and usually occurs in young children. It is a lobulated, localized (lipoblastoma) or diffuse (lipoblastomatosis) tumor, resembling fetal adipose tissue.

  salivary gland mucoepidermoid carcinoma PO WKP WP
  Definition: The mucoepidermoid carcinoma is the most common malignant neoplasm observed in the major and minor salivary glands.
  Mucoepidermoid carcinoma is the most common adult salivary malignancy. It histologically is non-encapsulated and shows three cell types - squamous, mucous and intermediate, and may show prominent oncocytic change. It is associated with t(11;19) fusing MECT1 and MAML2 (MAML2-MECT1 fusion gene).

  Angiomatoid "malignant" fibrous histiocytoma is considered to be a low-grade sarcoma of childhood, and, with its fibrous pseudocapsule, angiomatoid change, dense lymphoplasmacytic response, and proliferation of spindled or round cells, has been classified as a fibrohistiocytic neoplasm. (...)

• NUT midline carcinoma
  5 May 2009

  NUT-associated carcinoma NMC
  Definition: NUT midline carcinoma (NMC) is a high-grade malignancy that is defined by rearrangement of the nuclear protein in testis (NUT) gene on chromosome 15q14.
  NMCs are morphologically indistinguishable from other poorly differentiated carcinomas, and the diagnosis is usually made currently by fluorescence in situ hybridization (FISH).

• giant cell angiofibroma
  11 October 2005

  Definition: Giant cell angiofibroma is a phenotypic variant of solitary fibrous tumor (SFT).
  Giant cell angiofibroma seems most often to arise in the head and neck region (predominantly orbit) of adults and which, with the passage of time.
  It may well prove to be a variant of solitary fibrous tumour characterized by prominent multinucleate giant cells and lipofibromatosis.
  It is a rare tumour occurring predominantly in the hands or feet of infants and young children.
  it shows a high (...)
