  • pancreas
  • It now appears that cystadenomas without mesenchymal stroma appear to be more akin to similar cystic lesions of the pancreas, and may represent a dissimilar neoplasm. (biomedsearch.com)
  • Bert Vogelstein and his colleagues discovered that almost all of the precancerous cysts (intraductal papillary mucinous neoplasms) of the pancreas have mutations in the KRAS and/or the GNAS gene. (wikipedia.org)
  • Medical

  • lymphoid neoplasms
  • For lymphoid neoplasms, e.g. lymphoma and leukemia , clonality is proven by the amplification of a single rearrangement of their immunoglobulin gene (for B cell lesions) or T cell receptor gene (for T cell lesions). (wikipedia.org)
  • common
  • Neuroendocrine neoplams (NENs) are neoplasms with a broad range of morphologic patterns, grade of differentiation, and biological behavior that share common features of neuroendocrine (NE) programming. (springer.com)
