Small bowel biopsy in a 4-year-old girl with symptoms suggestive of co
eliac disease revealed subtotal villous atrophy. The mucosa healed on
a gluten-free diet. From the age of 7 years, the girl was challenged w
ith gluten. Annual biopsies showed normal or nearly normal mucosa spec
imens. At 21 years of age, after 14 years of gluten challenge, a mucos
al relapse was found and a gluten-free diet was reinstituted. A biopsy
one year later showed a normal mucosa. From this case report it is ap
parent that a patient with a past history of subtotal villous atrophy,
which after a preceding period of gluten-free diet does not recur wit
hin two years of gluten challenge, must be followed carefully, so as n
ot to miss a late relapse.
