RESUMO
Adenomyoma, a benign tumor generally considered to be a form of pancreatic heterotopia, is composed of smooth muscle and undifferentiated columnar epithelium. A 62-year-old female was admitted with melena. Small bowel enteroscopy using a pediatric colonoscope revealed a small sized nodular mass with active bleeding in the proximal jejunum. After a endoscopic resection of the tumor, the bleeding ceased. Histologic examination disclosed an adenomyoma. We report a case of the adenom-yoma causing jejunal bleeding with a review of the literature.

We experienced a case of primary gastric tuberculosis presented with melena. A 61-year-old male was admitted with epigastric pain and melena. Upper endoscopy revealed an irregular shaped gastric ulcer on the posterior wall of the body. Histological examination of endoscopic specimen revealed chronic inflammation with fibrosis, granulomas and acid-fast bacilli. Cultures for acid-fast bacilli subsequently grew Mycobacterium tuberculosis. There was no evidence of the tuberculous lesion anywhere else. Primary gastric tuberculosis remains an extremely uncommon clinical entity; the definitive diagnosis is made by biopsy and positive culture for the organism. We report a case of primary gastric tuberculosis with review of the literature.
