Upper gastrointestinal bleeding in a patient with Sjögren syndrome.

A 68-year-old female patient with Sjögren syndrome was admitted with asthenia, anorexia and weight loss. On the third day of admission, she developed severe hematemesis. Urgent upper gastrointestinal endoscopy (UGE) showed multiple gastric and duodenal ulcers, some with active bleeding requiring endoscopic therapy. The anatomopathologic examination was compatible with gastric and duodenal infiltration by a diffuse CD20+ large B cell lymphoma with germinal center B cell-like morphology. And the patient was referred for chemotherapy with rituximab, cyclophosphamide, doxorubicin, vincristine and prednisolone. Although seldom observed, the risk of lymphoma in Sjögren syndrome is up to 44 times higher than the general population and rises 7 years after diagnosis. We present a brief case report with interesting iconography.
