A case of multiple gastric carcinoid tumors associated with Sjogren's syndrome / 대한내과학회지

ABSTRACT

Carcinoid tumors are rare endocrine neoplasms arising from the enterochromaffin or enterochromaffin-like cells. Gastric carcinoids associated with autoimmune atrophic gastritis and hypergastrinemia, are usually multiple and the prognosis are better compared to solotary lesions with out hypergastrinemia. Gastric carcinoids are commonly associated with other endocrine disorders or tumors, but any associations with autoimmune disorders other than autoimmune atrophic gastritis have rarely been reported. Sjogren's syndrome is an autoimmune exocrinopathy that primarily affects the salivary glands, but it can also involve almost any other part of the gut. The most common form of gastrointestinal involvement in Sjogren's syndrome is chronic atrophic gastritis, which can lead to hypergastrinemia and the subsequent development of carcinoid. However, gastric carcinoid tumor associated with Sjogren's syndrome has not yet been reported on. To the best of our knowledge, this is the first such case in the world. We report on this case along with review of the related literature.
