• chromophobe hepatocellular carcinoma with abrupt anaplasia
  10 May 2013

  Hepatocellular carcinomas exhibit heterogeneous morphologies by routine light microscopy. Although some morphologies represent insignificant variations in growth patterns, others may represent unrecognized subtypes of hepatocellular carcinoma.
  Identification of these subtypes could lead to separation of hepatocellular carcinomas into discrete groups with unique underlying genetic changes, prognosis, or therapeutic responses.
  This subtype was characterized by a unique and consistent set of (...)

• hepatic peritumoral hyperplasia
  10 January 2013

  peritumoral hyperplasia of the liver
  Several cases of focal nodular hyperplasia (FNH) or similar hyperplastic lesions have been reported adjacent to hepatic neoplasms, including hepatocellular carcinoma, epithelioid haemangioendothelioma and hepatoblastoma.
  PTH is a hyperplastic response to increased blood flow in the peritumoral parenchyma.
  The increased flow occurs when portal vein invasion by a hypervascular tumour causes arterio-portal shunting.
  While PTH shares some morphological (...)

• hepatic infarct-like necrosis
  23 March 2012

  Infarct-like Necrosis of the liver
  The response of colorectal adenocarcinoma liver metastases to perioperative chemotherapy can be assessed histologically in partial hepatectomy specimens. Necrosis in this scenario may represent a lack of treatment effect or a therapeutic response to chemotherapy.
  Use of Tumor regression grade (TRG) did not demonstrate a significant difference in disease-free and overall survival.
  An infarct-like necrosis (ILN) represents a form of treatment effect and (...)
