Immunoproliferative small-intestinal disease: follow-up of an alpha-chain negative, lymphoma-free group

Six patients had the clinical and pathological features of immunoproliferative small-intestinal disease (IPSID). All were female with malabsorption or growth retardation in whom testing for alpha-heavy chains was repeatedly negative. They were followed for a mean of 7.5 years, during which time no significant alteration in the jejunal biopsy appearances of five patients has occurred, none have developed lymphomas.
