- Abstract
Cases of inflammatory type cancer have a relatively good prognosis among diffusely infiltrating colorectal cancers.1 We experienced an extremely rare case of submucosal invasive cancer showing a similar morphology to inflammatory type cancer.2-4 A man in his 50s was referred to us because of a positive fecal occult blood test. Colonoscopy showed unilateral stenosis in the sigmoid colon. The lesion showed Crohn's disease-like inflammation; there was inflammatory cell infiltration into all layers and numerous epithelioid cell granulomas were observed (Figs. The lesion showed Crohn's disease-like inflammation; there was inflammatory cell infiltration into all layers and lymphocyte aggregation, and numerous epithelioid cell granulomas were observed in the tissue surrounding of the tumor.
