Amyloidosis of the gastrointestinal tract. Clinical cases

Full Text:

Abstract

Amyloidosis is a group of diseases characterized by extracellular deposition of fibrillar protein (amyloid) in tissues and organs, consisting of β-sheet plates. The clinical manifestations and the endoscopic picture of amyloidosis are diverse and not very specific, which makes it difficult for specialists to make a diagnosis. The most common manifestations from the gastrointestinal tract are observed in AL-amyloidosis. The morphological diagnosis is made by detecting the characteristic apple-green birefringence in polarized light after staining with Congo red. This article presents clinical cases of diagnosis of amyloidosis of the gastrointestinal tract and modern literature data.
