  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).

  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.

  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.
