Green apple and red congo: atypical dysphagia colours

Abstract

Amyloidosis is a rare disease that consists of the extracellular deposition of insoluble protein subunits known as fibrils, resistant to proteolytic degradation. It can occur in any organ of the body, causing its slow and gradual failure.

Specific involvement of the gastrointestinal tract interferes with its structure and function, most commonly in the liver and small intestine, with esophageal involvement being a rare entity, and whose main clinical manifestation is reflux. On the other hand, presentation in the form of dysphagia is highly uncommon.

Keywords: esophageal amyloidosis, dysphagia, Congo red.
