A case of massive intestinal bleeding from jejunal diverticulum is describe. A 62-year-old man was refered to our hospital because of melena and anemia. After admission, he showed massive hematochezia with unstable vital sign. Esophagogastroduodenocopy and colonoscopy, selective abdominal angiography, and RBC bleeding scanning were performed to seek the cause of the intestinal bleeding, but none of these studies revealed the source of bleeding. The examination of small bowel with methylcellulose showed multiple small jejunal diverticuli and a large diverticulum. Resection of the involved portion of jejunum was performed. On pathological examination, two mucosal loss lesions were detected, but ulcer or arteriovenous malformation were not seen in the resected jejunal diverticulum. The patient showed no more intestinal bleeding after operation. Although jejunal diverticuli are rare, the careful search for this complication in a patient with intestinal bleding is important.

Kimura disease, which was initially described by Kimura et al. in 1948, is a rare entity that occurs primarily in Asian people characterized histopathologically by a lymphofolliculoid granuloma with infiltration of the mass and the surrounding tissue by eosinophils, often with concomitant peripheral blood eosinophilia and elevated serum Ig E. The kimura disease frequentlly involves head and neck region and reraly extrimities. When the disease involvews parotid gland, it is very difficult to differentiate clinically with parotid gland tumor. We have experienced a case of Kimura disease. The lesion was initially diagnosed as a parotid gland due to extensive fibrosis surrounding the mass. So, the mass excision was performed without clear identification of the facial nerve. The Kimura disease usually follows a benign course. But when this disease is confused with parotid gland tumor, there will be a danger of nerve injury due to difficulty in dissection of the extensive fibrotic soft tissue surrounding the parotid gland.
