• uterine endometrioid adenocarcinoma, FIGO grade 1
  25 November 2010

  type 1 endometrial carcinoma
  Definition: Relatively indolent tumors that arise in background of endometrial hyperplasia.
  According to one definition, when endometrial glands show a confluent pattern occupying at least 2x2 mm focus, the diagnosis of adenocarcinoma can be made. Smaller foci are labeled "complex endometrial hyperplasia".
  The diagnosis of endometrioid adenocarcinoma can also be made if there is extensive papillary pattern or infiltrative glands with desmoplastic response. (...)

• chondroblastic osteosarcoma
  26 May 2009

  Digital cases
  Case 115 : Chondroblastic osteosarcoma of the calcaneum
  Definition : Chondroblastic osteosarcoma (OS) accounts for about 25% of all cases of OS.
  Localization
  flat bones
  temporal bone (#20730902#)
  Macroscopy
  Grossly, an overt chondroid appearance is rare. This is probably secondary to the cartilage component being less well-formed, high grade, and mixing with non-chondroid elements resulting in a lack of large areas of pure chondroid differentiation and its attendant (...)

• noninvasive urothelial carcinoma of the bladder With glandular differentiation
  26 May 2009

  Noninvasive urothelial carcinoma (UC) with glandular differentiation in the absence of infiltrating carcinoma is a rare entity.

• oligodendroglial tumors with marked desmoplasia
  11 May 2011

  Oligodendroglial tumors with prominent desmoplasia are rare. Most cases demonstrate 1p19q codeletion and IDH1 mutations, and behave as expected for anaplastic oligodendroglial tumors.

• cystic neuroblastoma
  3 January 2007

  Cystic neuroblastoma (CN) is an unusual variant of neuroblastoma characterized by a grossly visible cyst(s) and almost always distinctive microcysts on light microscopy. Rarely, CN will appear solid grossly, but microcystification will be present.
  Synopsis
  favorable stage
  stroma-poor with low or intermediate mitotic-karyorhectic indices
  favorable biologic markers aneuploidy absence of N-myc amplificatio absence of chromosome 1p deletions
  clinical outcome excellent
