[Rosai-Dorfman disease of the mesenteric lymph nodes and appendix. Secondary to salmonellosis?].

A 28 year-old female patient was operated for acute abdominal pain. At the surgical intervention the mesenteric nodes turned out to be enlarged and the appendix was apparently normal. Microscopically, the changes observed were of the Rosai-Dorfman disease type in the appendix as well as in the nodes. A salmonella D was cultivated in the mesenteric nodes. This association, which has not been described in the literature, permits us to comment clinicopathological aspects, poorly defined, with special reference to the possibility that some instances of Rosai-Dorfman disease could be secondary to an infectious process.
