Abstract

A case of pernicious anemia associated with Hashimoto's thyroiditis who was found discolored annular zone in the stomach by endoscopic congo red test was reported. The patient, 56 years old female, has been diagnosed as pernicious anemia was treated with vitamine B₁₂ since 7 years before. She noticed general fatigue and facial edema. Thyroidal hypof unction, positive microsome test and thyroid test led to the diagnosis as Hashimoto's thyroiditis. Endoscopic examination showed severe atrophic gastritis in the body and discolored annular zone in the lower portion of the gastric body by congo red test. This may suggest that an autoimmune mechanism had related to the extension of this type-A gastritis. The discolored annular zone could be found in cases with other disease and may require further investigation.
