Protein-losing pseudomembranous colitis with cap polyposis-like features

Wolfgang Kreisel et al. World J Gastroenterol. .

Abstract

Protein-losing enteropathy (PLE) is characterized by loss of serum proteins into the gastrointestinal tract. It may lead to hypoproteinemia and clinically present as protein deficiency edema, ascites, pleural or pericardial effusion and/or malnutrition. In most cases the site of protein loss is the small intestine. Here we present an unusual case of severe PLE in a 55-year old female with a one-year history of recurrent diarrhea, crampy abdominal pain, and peripheral edema. Endoscopy and MRI showed a diffuse inflammatory thickening of the sigmoid colon and the rectum. Surgical resection of the involved colon was performed and the symptoms were significantly resolved. The final histologic evaluation confirmed a diagnosis of a pseudomembranous colitis with cap polyposis-like features. Such a cause of PLE has never been described before.

Histologic appearance of the colonic mucosa. A: Erosive lesions covered by a thick pseudomembranous layer; damage of the surface epithelium and architectural disarray of the mucosa showing prominent cystic dilatation of crypts; B: Foci of mildly serrated epithelium; C, D: Abundant hyperplastic goblet cells associated with a strikingly increased accumulation of intracellular and extracellular mucus. A-C: Hematoxylin and eosin; D: Periodic acid-Schiff reaction.

Typical features of protein-losing colitis demonstrated by immunohistochemistry and special stains. A: Strong cytokeratin 20 expression (brown) by hyperplastic and attenuated (arrows) epithelial cells; B: Detection of rare CD3+ T-cells (brown, arrows) in the lamina propria and epithelium; C: Acid fuchsin orange G-stain (AFOG) stain demonstrating proteins (red) in the apical part of the denuded crypts; the granulation tissue and the pseudomembranes covering the surface, but not in the deeper parts of the mucosa; D, E: AFOG stain combined with a PAS reaction highlighting the presence of both proteins (red) and admixed mucus (pale pink, stars); E: Abundant pale pink mucus (star) but no significant proteins in the crypts lined by hyperplastic goblet cells.
