Primary Sjögren's syndrome associated with chronic atrophic gastritis and pernicious anemia

Sjögren's syndrome (SS) is a systemic, autoimmune exocrinopathy in which destructive, inflammatory-cell infiltration can affect any gland. Although chronic atrophic gastritis is the most common form of gastrointestinal involvement in SS, pernicious anemia develops in rare cases. We therefore report a patient with these three associated diseases.
