• infectious agents in histiocytes
  6 May 2019

  The presence of an infections agent in the cytoplasm of histiocytes makes the diagnosis of an infections disease with histiocytic reation.
  For example :
  AARB with Ziehl : mycobacterosis as tuberculoses or lepra
  deep fungal diseases as histoplasmosis

• glandular metaplasia

  Definition : Glandular metaplasia is a type of metaplasia where irritated tissue converts to a glandular form.
  An example occurs in the esophagus, where tissue becomes more similar to the tissue of the stomach. Another example occurs in the urinary bladder : vesical glandular metaplasia.

• mucinous differentiation
  17 February 2019

  mucinous metaplasia
  Examples
  acral acrospiroma with mucinous differentiation Mutinous differentiation in sweat gland tumors / eccrine tumors , is defined by the presence of goblet cells and/or intracellular mucicarmine positivity. It is common and does not indicate aggressive behavior. Mucinous differentiation in benign sweat gland tumors should not be confused with more aggressive mucoepidermoid carcinomas of salivary gland origin or adenosquamous carcinoma.

  Pathology
  extracellular deposits Example : amyloidosis Amyloidosis is a group of diseases in which an abnormal protein, known as amyloid fibrils, make deposits in the extracellular space. Amyloidosis is not a single disease but a term for diseases that share a common feature : the extracellular deposition of pathologic insoluble fibrillar proteins in organs and tissues.
