  myxoid liposarcoma and round cell liposarcoma group; MRC-LPS
  Definition: Myxoid and round cell liposarcoma accounts for about 30% to 35% of all liposarcomas and, even if still classified by the World Health Organization (WHO) as 2 distinct subtypes, share both clinical and morphologic features.

• 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.

  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. (...)

  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).
