RESUMO
Waldenstrom's macroglobulinemia is a disorder of malignant proliferation of plasmacytoid lymphocytes and monoclonal immunoglobulin M. However, the patients occasionally present with malabsorption and diarrhea due to deposition of extracellular periodic acid-Schiff positive homogenous eosinophilic, amorphorous, and proteinaceous materials in the villi and/or lamina propria of the duodenum. We report a 62-year-old man who, despite involvement of the duodenal mucosa, presented only with fatigue, dypnea on exertion, and anemia. Characteristic duodenoscopic and pathologic findings of this patient are described.

Hemangioma in the gastrointestinal tract rarely occurs especially in the stomach compared with the small and large intestine. A 45-year-old man was admitted with pneumonia. After hematemesis, the authors performed gastroscopy, which revealed active bleeding on the huge ulcer on the antrum of the stomach and multiple erosive lesions on the whole stomach. After multiple submucosal hypertonic saline injection and hemoclipping at the huge ulcerative lesion, ulcer bleeding stopped. Three days later, recurrent massive upper gastrointestinal bleeding occured at the same site of the stomach. To prevent futher recurrent bleeding, total gastrectomy with esophagojejunostomy and splenectomy was done. The histologic diagnosis of the ulcerative lesion was hemangioma of mixed type. We report this rare case with the brief literature review.
