Colonic mucosa-associated lymphoid tissue (MALT) lymphomas are rare and a definitive treatment has not been established. Solitary or multiple, elevated or polypoid lesions are the usual appearances of MALT lymphoma in the colon and sometimes the surface may reveal abnormal vascularity. In this paper we report our experience with four cases of colonic MALT lymphoma and review the relevant litera...

We encountered a patient with pathologically proven primary appendiceal lymphoma associated with acute and chronic appendicitis. Ultrasonograp h y revealed a non-compressible sausage-shaped hypoechoic mass with a linear hyperechoi...

A CT colonography was carried out to exclude colonic malignancy. Unilateral gallbladder w...
