Extensively infiltrating colon adenocarcinoma similar to Crohn's disease: a case report.
A 38-year-old Chinese man presenting with chronic diarrhea and secondary incomplete intestinal obstruction was hospitalized in April 2010. Electronic colonoscopy and barium enema examination initially showed longitudinal scar-like strictures and cobblestone appearance in the colon that was similar to those in Crohn's disease. After subtotal colectomy and partial intestinal resection, the pathological examination indicated colon adenocarcinoma that diffusely infiltrated along the colon longitudinal axis rather than the initial diagnosis of Crohn's disease. Pathological examination revealed colon adenocarcinoma with excessive desmoplastic reaction and infiltrating cancer cells along the colon longitudinal axis that may have accounted for the morphological similarities to Crohn's disease in this case. The findings in the present case suggest that colon carcinoma should be considered when Crohn's disease-like findings are encountered, not only in individuals with concurrent cancer in other sites, but also in patients with a long history of gastrointestinal symptoms such as chronic diarrhea or abdominal pain.
