Sarcomatoid carcinoma in a patients with Sjogren's syndrome

Sarcomatoid carcinoma is an extremely rare small bowel tumor whose clinical manifestations are insidious and nonspecific, ranging from diffuse abdominal pain to gastrointestinal bleeding or intestinal occlusion. Thus, diagnostic delay is highly common with poor treatment outcome and prognosis. To date, only 20 cases have been reported in the literature. We describe the case of a small bowel sarcomatoid carcinoma localized in the jejunum, with emphasis on the clinical and pathological features of this entity. The hypothetical association with Sjogren's syndrome, an autoimmune disease, is also discussed. (C) 2008 Elsevier Espana, S.L. All rights reserved.
