Very few cases of rheumatoid arthritis combined with pernicious anemia have been reported in the world literature and none in the Chinese literature. A 62-year-old female initially presented with anemia. Pernicious anemia was diagnosed by characteristic blood and bone marrow morphology. Laboratory data showed a deficiency of vitamin B12 and positive anti-gastric parietal cell antibodies. Her anemia improved after vitamin B12 therapy. Painful swelling of multiple joints developed 6 years later. The clinical presentation supported a diagnosis of rheumatoid arthritis. We report herein a rare case of rheumatoid arthritis and pernicious anemia in the same ethnic Chinese patient. We also review the literature and discuss a possible association between a non-organ-specific autoimmune disease, rheumatoid arthritis, and an organ-specific autoimmune disease, pernicious anemia.
