A Case of Duodenal Amyloidosis Accompanied with Candidiasis that was Diagnosed by Endoscopy / 대한소화기내시경학회지

ABSTRACT

This report describes a case of a 63-year-old female who suffered from gastrointestinal amyloidosis. The patient presented with abdominal pain, nausea, vomiting and watery diarrhea for a week. Previously, the patient had been treated for rheumatoid arthritis. Endoscopy showed the presence of erythematous mucosa and yellowish exudates in the bulb, a finding that was compatible with duodenal candidiasis. Colonoscopy showed diffuse erythematous and easy friability in the entire colon, a finding suggestive of infectious colitis. The pathology report indicated that the lesion had amyloid, which was stained by Congo red. Endoscopic findings of amyloidosis are non-specific, such as friable mucosa, granulation, polyp, erosion and ulceration. Therefore, it is difficult to diagnose amyloidosis with endoscopic findings. However, if the patient has risk factors of secondary amyloidosis such as rheumatoid arthritis, gastrointestinal amyloidosis based on the endoscopic finding should be considered. We report a case of duodenal amyloidosis accompanied with candidiasis, which has not been previously reported.
