摘要

Russell bodies are eosinophilic intracytoplasmicglobules which are likely the result of disturbedsecretion of immunoglobulins that accumulate withinthe plasma cell. Russell body collections have beenidentified within the stomach, known as Russellbody gastritis. Similar lesions within the duodenumare referred to as Russell body duodenitis, whichis rare. Several Russell body gastritis case reportsare associated with Helicobacter pylori . However,the etiology of Russell body duodenitis remainsunclear. Here we report the first case of Russell bodyduodenitis with immunoglobulin light chain restrictionin a background of peptic duodenitis.
