Amyloidosis presenting as melaena
Amyloidosis is a disease characterized by abnormal extracellular deposits of protein. The disease may affect the stomach, however, symptoms are rare in this case. Furthermore, the rare symptoms are diffuse and unspecific and the diagnosis relies on biopsy. We report the case of a 79-year-old female presenting with melaena and no history of amyloidosis. Gastroscopy raised suspicion of a malignant process in the stomach, but biopsy revealed gastric amyloidosis. The treatment of gastric involvement is primarily symptomatic, and causal treatment is reserved for the few.
