  Juvenile polyposis syndrome; JPS; JPD; Juvenile polyposis disease; digestive juvenile polyposis
  Autosomal dominant disease.
  JPS presents in childhood or adulthood with a history of rectal bleeding. The juvenile polyps may be limited to the colorectum or generalized throughout the gastrointestinal tract. Rarely, the stomach is the principal site of involvement.

  Inflammatory Fibroid Polyps of the Gastrointestinal Tract WP
  Definition: Inflammatory fibroid polyps (IFPs) are rare mesenchymal tumors of the gastrointestinal tract that consist of spindle-shaped stromal cells and an inflammatory infiltrate rich in eosinophils. Their etiology and histogenesis remain unknown.
  Inflammatory fibroid polyp, abbreviated IFP, is a benign abnormal growth of tissue projecting into the lumen of the gastrointestinal tract. The endoscopic differential diagnosis (...)

• M cells
  4 December 2003

  Function
  The M cell is found in the epithelium that covers mucosa-associated lymphoid tissue in the digestive tract and the airways.
  M cells internalize macromolecules and microorganisms efficiently and deliver them to the underlying lymphoid tissue.
  In the gut, M cells, unlike the neighbouring absorptive enterocytes, lack a highly organized apical brush border and glycocalyx, and are poorly equipped with digestive enzymes.

• digestive vasculitis
  18 November 2003

  Vasculitides can cause local or diffuse pathologic changes in the gastrointestinal tract, resulting in nonspecific paralytic ileus, mesenteric ischemia, submucosal edema and hemorrhage, or bowel perforation or stricture.
  The extent and clinical course of disease depend on the size and location of the affected vessel and the histologic characteristics of the lesion.
  Vasculitis may primarily involve large vessels (eg, giant cell arteritis, Takayasu arteritis), medium-sized vessels (eg, (...)
