Abstract

A 35-year-old man was admitted to the hospital because of anal bleeding, abdominal pain, and frequent diarrhea. On admission, there were peritoneal sign. hyperleukocytosis, and ascites on an abdominal CT scan. An emergency operation was performed with a diagnosis of generalized peritonitis. During surgery, about 300ml of light yellowish and slightly muddy ascites and congestion and mild edema on serosa of the ileum covering about 45cm about 60cm oral side from the ileocecal region were noted. A partial excision of the ileum was performed. The excised material revealed five relatively shallow concave lesions, 5_??_7mm in diameter and small circule in shape. Histopathologic and immunohistochemical studies disclosed that the concave lesion were MALT lymphoma.
MALT lymphomas of the small intestine are relatively rare, and the case of MALT lymphoma of the small intestine with ascites is presented together with some bibliographical comments.
