Newly Diagnosed Colonic Adenocarcinoma: The Presenting Sign in a Young Woman with Undiagnosed Crohn’s Disease in the Absence of Primary Sclerosing Cholangitis and a Normal Microsatellite Instability Profile

<div>H&amp;E stained sections of grade 2 (moderately differentiated) adenocarcinoma extending through the muscularis propria (pT3). (a) Full-thickness section of the tumor. Adjacent to the tumor and deep to the tumor are lymphoid aggregates composed of tumor infiltrating lymphocytes (20x), (b) areas of tumor highlighting predominantly moderate differentiation (40x), (c) areas of tumor highlighting poor differentiation comprising less than 5% of the overall tumor (40x), (d) tumor originating from surface epithelium (40x), (e) and lymph node metastasis (20x).</div>
