| Abstract: | Collagenous colitis is a clinicopathologic syndrome characterized by chronic watery diarrhea and unique histopathologic features. Spontaneous colonic perforation in the setting of collagenous colitis is a highly unusual complication, with only three cases reported in the literature to date. We present a fourth case and propose a potential pathologic mechanism for acute colonic perforation in this patient population. |
