Collagenous colitis: a transient condition? Report of two cases.
We have seen two patients with watery diarrhea whose work-up revealed a collagenous infiltration beneath the rectal epithelium. Within a year, symptoms disappeared in both. Repeated rectal biopsy revealed the disappearance of the collagen layer. Collagenous colitis may thus present as a transient condition.
