-Abstract-
Extranodal mucosa-associated lymphoid tissue (MALT) lymphoma constitutes most of
the low-grade gastric lymphoma and almost 50％ of all gastric lymphoma. The specific
recirculation pattern might explain the tendencies of MALT lymphomas to remain
localized and to recur preferentially within the gastrointestinal tract. It was known that
the rate of gastric MALT lymphoma with bone marrow involvement was low, as less
than 10％. We have experienced two patients who presented with nonspecific abdominal
pain and dyspepsia. They were diagnosed to have gastric low-grade MALT lymphoma
with bone marrow involvement at the time of presentation. The endoscopic findings
showed irregular ulcerations. Microscopically, there was monotonous lymphoid infiltration
with lymphoepithelial lesions which were consistent with low grade MALT lymphoma.
Both patients showed H. pylori-associated chronic gastritis. The results of their bone
marrow biopsy showed focal infiltration of neoplastic lymphoid cells. We report two
cases of primary gastric low-grade MALT lymphoma with the bone marrow
involvement.
