Towards a new paradigm of microscopic colitis: Incomplete and variant forms

Figure 6 Photomicrographs of a colonic specimen from a healthy donor. Hematoxylin-eosin staining, magnification × 100 (A) showing low number (usually less than 5) of intraepithelial lymphocyte cells, which can be easily identified by CD3 immunohistochemistry marker (B, magnification × 100). The subepithelial collagen band is tiny and regular (C, Gomori’s Trichrome staining, magnification × 10 and inset, Gomori’s Trichrome staining, magnification × 400).
