• 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. (...)

  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 (...)

• epithelioid inflammatory myofibroblastic sarcoma
  24 December 2010

  Definition: Epithelioid inflammatory myofibroblastic sarcoma is an aggressive intra-abdominal variant of inflammatory myofibroblastic tumor With nuclear membrane or perinuclear ALK. (#21164297#)
  Inflammatory myofibroblastic tumor (IMT) is a mesenchymal neoplasm of intermediate biological potential, which may recur and rarely metastasize. Pathologic features do not correlate well with behavior.
  Approximately 50% of conventional IMTs harbor ALK gene rearrangement and overexpress ALK, most (...)
